TetherGeist review — O. & Co. Games' debut precision platformer, out May 7, 2026 on Steam and Switch.
Key Takeaways
- TetherGeist is a combat-free precision platformer built entirely around Astral Projection — a tether mechanic connecting Mae to her axolotl spirit, Bao
- Seven distinct Azae items change how the spirit interacts with each environment, forcing you to relearn movement logic in every region
- Mae has a motor disability and chronic illness; the game ties this directly to the mechanics, not just the story
- BIG Festival finalist in four categories: Best Game, Best Art, Best Sound, Best Impact
- Frequent checkpoints and instant retries keep the difficulty steep but not sadistic
The tethergeist review most critics have written focuses on one question: is this the next Celeste? That's the wrong frame. O. & Co. Games' debut title shares Celeste's commitment to movement-as-metaphor and its willingness to make you fail hundreds of times. But TetherGeist's Azae system asks something different of the player — not reflexes, but geometric reasoning. That's a harder sell, and a more interesting one.
Overview
TetherGeist follows Mae, a young villager with a motor disability and chronic illness, preparing for a once-in-a-lifetime religious pilgrimage. Her companion is Bao, an axolotl spirit bound to her through Astral Projection — a tether ability that extends Mae's spirit outward like a grappling hook. This is the game's single mechanical throughline. There's no combat, no upgrade tree, no inventory to manage. You move through the world by projecting Bao into it.
The game was funded on Kickstarter — 500 backers, $21,445 raised — with characters co-designed through backer input. Several NPCs in the finished game reflect that collaboration directly. O. & Co. Games is a debut studio, and TetherGeist was named a finalist in four categories at the BIG Festival (Best Game, Best Art, Best Sound, Best Impact) before launch. The demo on Steam pulled 98% positive from 74 reviews. Expectations were reasonable.
The full game largely meets them, with one persistent friction point.
Gameplay: The Tether Mechanic
The Astral Projection system is the reason to play TetherGeist. Mae can extend Bao outward into the level and then interact with what Bao touches — depending on which Azae item she's currently carrying. There are seven different Azae across the game's chapters, and they don't function as simple power upgrades. Each one changes the fundamental logic of how you interact with the environment.
The tether mid-pull in a spiked corridor — the entire game's movement language comes down to this moment.
The first Azae you get does something straightforward: project Bao a short distance, then teleport to where Bao lands. This is the genre-standard grapple. You learn the input, you learn the range, you move on. The second major Azae is where TetherGeist earns its identity. This one sends Bao out as a ball in a straight line — but Bao banks off walls and passes through thorny obstacles that would kill Mae on contact. You're no longer just aiming at a landing spot. You're calculating angles, accounting for bounces, reading a level geometry that suddenly means something different than it did three screens ago.
The mushroom-power Azae is the game's hardest ask. It bounces Mae toward or away from floating mushrooms based on her approach angle. There's no mid-air correction once you commit. You're either at the right angle or you're reloading the checkpoint. A handful of the game's more punishing sequences rely on this Azae, and they're where the "sometimes a little too difficult" critiques come from. The margin for error is genuinely small, and the feedback when you fail doesn't tell you how far off your angle was.
What keeps the system from collapsing into frustration is the level structure. Each screen is bite-sized — rarely more than thirty seconds of movement — and checkpoints appear frequently within levels, not just between them. Instant retries mean a failed attempt costs you seconds, not minutes. This is the same design choice Celeste made, and it's the right one. Failure is information, not punishment.
Each region of the game tweaks how the Azae interact with environmental objects, which means you can't stop learning. An Azae that felt solved three chapters ago will start behaving unexpectedly when a new obstacle type enters the picture. This design keeps the game's 7–10 hour runtime from becoming routine, though it also means some players will hit a wall when a new rule set appears with minimal explanation.
The competitors covering this game describe the Azae system at a high level — "seven different abilities" — but mostly stop there. The specific interaction rules matter: the ball-Azae's wall-banking behavior is what makes certain puzzle screens work, and the mushroom Azae's angle-dependency is what makes them occasionally feel unfair. Those aren't the same thing.
Difficulty and Accessibility
TetherGeist is genuinely hard. This is not a game that softens its challenges for narrative reasons, even though its protagonist lives with a motor disability. That choice is deliberate, and worth noting.
The accessibility panel — TetherGeist's assist modes are unusually granular for a precision platformer.
Mae's disability shapes her story but doesn't limit what the player can do. The Astral Projection system — the tether — is framed as the way Mae moves through a world her body makes difficult. This isn't a metaphor that collapses under scrutiny. The act of controlling Bao remotely while Mae's physical form stays planted is the game, mechanically. The narrative and the mechanics point at the same thing.
The NPC cast reflects similar attention. Foyal wrestles with faith. Other characters carry class anxieties, cultural identities, diverse backgrounds. These aren't token inclusions. The writing is specific enough to feel like it came from real conversations, which tracks — the Kickstarter campaign involved backers in character development.
For accessibility mechanics specifically: the frequent checkpoints and instant retries are the primary tools. The game also ships with six language options (English, German, Japanese, Brazilian Portuguese, Simplified Chinese, Latin American Spanish) with full subtitles. There's no built-in assist mode equivalent to Celeste's — if the mushroom-angle problem has you stuck, the only official tool is the checkpoint density. That's a real gap for some players.
Nintendo Life called TetherGeist their favourite 2D platformer since Celeste while noting a flat narrative in places and some minor visual bugs. TechRaptor described it in their TetherGeist review as "a challenging precision platformer with a solid narrative" that's "at times a little too difficult" but worth seeing through. That range reflects the game accurately.
Note: The specific price for TetherGeist was not publicly listed at the time of this review. The developers indicated pre-launch that pricing would be in the Celeste/Hollow Knight range (~$15–$20). Check the TetherGeist Steam page for current pricing.
For players coming from REPLACED — the cyberpunk 2.5D action platformer that launched earlier this year — TetherGeist will feel dramatically lighter mechanically but emotionally heavier. There's no combat loop to fall back on when the movement doesn't click. See our REPLACED review for context on where the genre bar sits in 2026.

Verdict
This TetherGeist review comes down to one question: does the Azae system justify the difficulty? It does — mostly. O. & Co. Games' debut is one of the more ambitious debuts in the precision platformer space in recent years. The Azae system does something most movement games avoid: it forces you to relearn, repeatedly, across the entire game. That's a harder design problem than building a single elegant mechanic and iterating on it. They mostly solve it. The mushroom Azae is a specific exception — the angle-dependency without visual feedback creates genuine unfairness in a handful of screens.
The narrative is the more unexpected strength. Disability representation in games usually takes one of two forms: the disability as obstacle to be overcome, or the disability ignored entirely. TetherGeist threads a third path — Mae's condition is real, shapes how NPCs interact with her, and connects directly to the core mechanic. That's not a small achievement for a Kickstarter-funded debut.
The flat narrative patches that Nintendo Life noted are real. Some NPC conversations retread emotional territory that earlier interactions already covered. The visual bugs they mentioned are minor but present.
At $15–$20 range, TetherGeist is worth the failure. The Azae system will make you think differently about precision platformer level design, and Mae's story is worth seeing through to the end. This is what a meaningful debut looks like — not flawless, but genuinely adding something to the genre.

Frequently Asked Questions
Is TetherGeist harder than Celeste? TetherGeist is comparable in raw difficulty to Celeste's main campaign, but the challenge comes from a different place. Celeste tests muscle memory; TetherGeist tests geometry. Each Azae ability changes the logic of how you move, so you're constantly relearning rather than perfecting a single technique. Some players find this more mentally taxing, even if individual screens are shorter.
What are the seven Azae in TetherGeist? The game doesn't name all seven upfront — they're introduced progressively across chapters. The first lets Mae project her spirit a short distance and teleport to it. A later one sends the spirit as a ball that banks off walls and passes through thorny obstacles. The mushroom Azae bounces Mae toward or away from floating mushrooms based on approach angle. Each new Azae changes how existing environmental obstacles behave, so earlier areas can feel different on return visits.
Does TetherGeist have accessibility options? Yes. The game uses frequent in-level checkpoints and instant retries, so death rarely means replaying more than a few seconds. It also supports six languages with full subtitles. It does not appear to have an assist mode equivalent to Celeste's — the checkpoints are the primary difficulty mitigation tool.
What platforms is TetherGeist on? TetherGeist launched May 7, 2026 on Steam (PC) and Nintendo Switch. The Nintendo Switch version is also compatible with Nintendo Switch 2. Both versions launched simultaneously.
Is TetherGeist about disability? Disability is central to the narrative. Mae lives with a motor disability and chronic illness, and the story explicitly connects this to her Astral Projection ability — her spiritual tether is the way she navigates a world her body makes difficult. The game also covers class, spirituality, and social dynamics through its NPC cast.
How long is TetherGeist? Exact completion times haven't been widely documented yet, but based on the demo scope and level structure, a first playthrough is likely 6–10 hours for average precision platformer players. Players who struggle with the geometric angle-reading required by later Azae may take longer.
Was TetherGeist successful on Kickstarter? TetherGeist raised $21,445 from 500 backers. The campaign was notable for involving backers in character design — several NPCs reflect backer input directly. The demo accumulated 74 reviews at 98% positive before launch.
