I beat all 20! really interesting idea. though the first like 5 levels I accidently won just moving the mouse left and right before I knew what was going on. I ended up reading the controls and got the hang of it! Overall, a really fun game.
My idea was to make puzzle solve themselves so the player goes "wait a minute, what happened?" and then introduce some levels where it doesn't work and you have to think, I might have been a bit too much on the side of the levels solving themselves :P
