About this game

A side-scrolling, action-puzzler with "Very Positive" reviews on Steam. Come adventure and explore on the soon to be released mobile version.

▶Uncover the truth hidden in the sinister shadows of this ghastly environment
Awakening inside a dark, humid, and abandoned laboratory, MO discovers that it not only has to face an extremely hostile and sinister environment, but also humans who, having been taken over by alien parasitic plants, are now stuck in an endless limbo between death and rebirth. Who caused this disaster? And on this path to solve the riddle of MO's existence, what sorts of trials and tribulations lie ahead?

▶Clear quests with intertwining puzzles using strategic battle skills
360-degree gameplay that combines action and puzzle-solving. Use MO's ability to stick on surfaces to get past tricky traps, read the minds of monsters, control them like a parasite, and dash past danger as you fly through the air.

▶Exceptionally unique environmental design
MO has an exquisite pixel art that is both adorable yet dark, giving the game a full-bodied sci-fi atmosphere. Besides fitting the storyline perfectly, the amazing aesthetic effects are a constant visual feast for players as they adventure onward.

▶A soundtrack that is elegant and emotionally moving
The game's theme song has been carefully crafted to express the story of MO's adventure, while the background music and sound effects for each quest fit perfectly with each environment.

▶Collaborating to create a moving masterpiece
An exceptional masterpiece, developed by Archpray Inc. and produced by Rayark Inc.

*CONTROLLER STRONGLY RECOMMENDED* for enjoyable controls. With that out of the way, the gameplay is very smooth and controls are tight. The story is interesting and uncovered in multiple ways. Wonderful art, music, and addicting puzzles, frequent checkpoints. There isn't any traditional combat, even in boss fights it's all about figuring out the weakness, dodging, and jumping. I totally recommend this game.

Felt like updating my review of this game for 2026 and it's truly a great experience. It has great visuals, great audio, challenging puzzles and combat, plus the story is engaging enough to keep you playing to completion. While not perfect it is definitely worth your time.

Overall pretty flawless game, with well functioning touch controls. However, there are two issues. Firstly, the battery drain is a bit on the heavier side, about 10-12% drop within 30 minutes (android 14, SD 888), and secondly, the device gets pretty warm (no excessive heat though) when playing. I'm not sure about the phone getting warm thing, maybe that's within acceptable limits, but the battery drain is noticeable. The game is superb (about 9-9.5hrs long) and the cloud save works fine too.
