The gameplay is basic but fun. I had a pretty nasty bug that wouldn't let me get past the tutorial level, the transitions were busted on it. But I reset the game a few times and then it worked. Good job though, I got all the stars!
Thanks for the review and for the full walkthrough of the demo! I know about the tutorial level bug, but unfortunately I found out about it the day after the game was posted when I gave it to a friend to play, and even more unfortunately I have no idea why this bug can happen, I checked the code several times but didn't find any errors :( (if I restarted the tutorial level through the level select menu, the bug disappeared for me, that's even weirder)
