Nice game, it started very promising with cool music and colorful menu. However, the tutorial feels a bit out of place, as it's unnecessarily difficult and it's not like the rest of the game. Otherwise, it's all  pretty good, with some creative levels. 

Good job on your first game in just 2 days! The game is very hard because you have no sense of knowing where you're standing. I think with a little bit more time, the game will be more fun.

Hopefully you learned a lot from making your first game. Keep it up man :)
