Wow, really cool game, well done. Your tutorial is great - it's a bit wordy, but it helped me to pick up the game play first go, and then stick around to try to beat your high score (which I wasn't able to do). I agree with a lot of the suggestions for improvement - but this is a really impressive game for a 48 hour jam. A fun and challenging game, with good bug-free mechanics and a great soundscape.
