The puzzles in this game were very good, hard enough to challenging but not too hard such that I had no idea what to do, definitely well balanced. The art lends itself well to the game I'd say, with more time I think some extra visual effects could be cool, like a little splash of colour when hitting against a wall. Sound and music are definitely lacking though I totally understand why since the time limit of the jam doesn't allow for everything you want to be added, very nice job anyway :)
