took off a point for sound :P
But you still get my 5. I think the hardest part of making this game was the making of the puzzles, nevermind having to solve them.
I'm on lvl23 I find it to be the most challenging lvl yet, 16 was hard, but then I just tried new ways for everything and eventually got it, and then 19 was hard for a while but then I found an easy way.
23... just.. keep trapping the purple square...
