- Feel: Steer an earthworm digging underground—push blocks, flip switches, eat apples; stuck? snip yourself in two and puzzle with an extra helper.
- Story: No big plot arc—just drill down level by level, solving and picking up secrets; the cut-off half becomes a "new friend."
- Hook: Snake body and Sokoban-style pushes share one grid; cutting yourself into a helper is rare, and egg-escort stages make you baby fragile cargo.
- Look & sound: Cartoon underworld—dirt, apples, hats read at a glance; demo takes say the art and undo both have personality, not photoreal.
- Mood: Light brain-burn, not scary; the answer is sometimes right there, and you sit blank for minutes before it clicks.
- Polish: Steam launch 2026-10-21; CN ¥42 (launch ~¥35.70); "Very Positive" ~100% (~20 reviews); Win/Mac/Linux/Steam Deck, full controller, ~500 MB install.
- Length & value: Four worlds, 50+ stages plus secrets; a ~forty-yuan bite-size puzzler, with a free Demo to try first.
- Scope: Stays on the underground puzzle line—push, eat, snip, escort eggs—no bolted-on adventure or combat.
- Similar: Grid spatial puzzles near Snakebird; fans of weird rules will also think of Baba Is You-style brain teasers.
