Welcome to "blue orange thing idk." In this game, you use the arrow keys to move your soul. What does that mean for mobile people? Too bad, so sad. Blue means to stay still, and orange means to move. If it was a regular Undertale game, you would lose hp if you screwed up. However in this game, you get some feedback instead. Use "Z" to change the attacking speed by 0.5 to make it slower. "X" to make it faster.
*TobyFox for concept *Some random Undertale game on Scratch for the soul sprite Also the box has no purpose you can just go outside it. nvm fixed Real men play on 0 speed
