What players say
Overwhelmingly positive: players praise its brutal, detailed injury system and emotional weight, while complaints centre on crafting, late-layer design and missing quality-of-life features.
Most players recommend the game and say it is punishing but fair, with a detailed health system where injuries, infections and exhaustion shape every run, and deaths that feel like lessons rather than losses. Many praise the atmosphere, soundtrack and the way the player's empathy for the small creature they control is built into the design. Some players say the layers and difficulty settings offer real replay value. Criticism focuses on crafting, which some find oppressive or unclear, on the later layers feeling like rushed dashes with little to gather, and on missing quality-of-life features such as selling items or saving mid-run. Some players call the tutorial locked behind progress a barrier, and a few note an audio issue with the health menu. Recent reviews are more mixed than the overall totals, with more reviewers saying the full release changed little compared with the demo.
Praised
- Detailed injury and health system
Players enjoy the deep medical simulation, where every wound, infection and exhaustion has consequences that shape how they play.
Many players - Emotional bond with the creature
Players say the fragile, sympathetic protagonist makes suffering and failure hit hard and makes them care about each run.
Many players - Atmosphere, art and sound
Players praise the dark pixel visuals, the soundtrack and sound design, which fade in and out as the situation calls for them.
Many players - Replay value and settings
Players value the generated worlds, character options, challenge modes and difficulty sliders, which keep runs varied.
Some players
Criticised
- Crafting is oppressive or unclear
Players find crafting hard to start, frustrating to get right and poorly explained, especially early on when materials are scarce.
Many players - Late layers feel empty
Players say the later layers are rushed dashes toward an objective with little to gather or do, and some find the new layers repetitive.
Some players - Missing quality-of-life features
Players miss basic conveniences such as selling items, saving and quitting mid-run, and muting the health menu sounds, which they consider overdue.
Some players - Unforgiving early game and tutorial
Players find the start overwhelming, with the tutorial locked behind progress and movement or water causing sudden, unfair deaths.
Some players
- Who it suits
- Players who enjoy punishing, detailed survival roguelikes and don't mind learning through repeated failure, and players who like emotional, dark stories told through gameplay.
- Who should skip it
- Players who want forgiving pacing, a smooth early tutorial or a long late game, and anyone who finds graphic injuries or distressing content hard to handle.
Short vs. long playtime: Players with more hours tend to praise the depth of the systems and the late-game challenge, while newer players more often criticise the early overload, the tutorial and the crafting.
