Really nice game, good framerate, interesting puzzle mechanics.
I can't remember all the formulas. It's a little frustrating to know I have the tools in my toolbox but not an easy way to figure out what they are or how to use them. This is the main reason I didn't finish the game.
I know this is a tutorial but the mechanics are introduced too fast. If this was a full game, a longer tutorial introducing one mechanic per level would be nice. But I know you have time constraints here. Also, I found the movement sound a little grating after a while.
Giving you a bit of harsh feedback here but that's because this game probably has some of the best ideas I've seen this game. Really good job! keep making games!
