Ah, I completely forgot about moving the paper around, haha. Yeah, it's a very enjoyable game - but I think the freedom that you have as a player might make it a little difficult as a puzzle game. In level 7, there were a lot of possibilities to complete it, but I couldn't find one. The solution space was very large and expansive - and puzzles are largely about reducing possible solutions to just one (process of elimination). Thanks for the hint!
