Nice puzzle game! Glad I stuck with it, after reading the game page and tutorial I thought I knew exactly what to do, but then I really had trouble seeing the gaps between the tiles on the very first level. I wonder if a lot of other people got stuck at that point and moved on. :/
Music is catchy, and puzzles are good. Just a few quality-of-life changes like making the gaps obvious at the start, and allowing all mouse control would help this game a lot imho! Great submission though. :)
