▶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.

Pretty darn good

Lots to love, great story, and responsive controls.

My only complaint is the lighting is really bad at parts. I spent over 20 minutes on a level in one room. Not because I was stuck on a puzzle or couldn’t succeed at platforming, but because I couldn’t see a tunnel opening along a stretch of wall I needed to enter.

An amazing game, An amazing experience

I originally purchased this game on the Pc, I’m just here to buy and support the creators and to let you guys know you’re in for an amazing experience. The music is wonderful, the graphics are wonderful, the story and the environment can weave an amazing story for you! The amount of love and hard work in this game is truly evident from the first “jump” to the first boss and first puzzle. This was a game made with heart, detail, and beauty. Have a lot of fun gamers, this is one is a beauty.

But it all comes down to when the game came out because... THIS GAME IS AWESOME!! Like how do I describe it?!?! The games story is really good, the game is not to hard nor to easy, and the game itself is just Beautiful! Thanks Rayark for giving us this awesome game! :)
