Very good game, with a minor flaw on level 29...
The game itself was very well made, and I'm laughing at the people who had problems with number 23, took me 4 trys :P Anyway, there seems to be a problem with level 29, because I had collected all the stars several times by flying around the the spike walls and picking up the remaining ones on the outside, but it didn't complete the level. I beat the game eventually however (funny ending) and it was very good. Just letting you know incase you made a little anti cheat barrier there, or just a small gltich. Keep up the good work!
