Hi! I'm happy that you liked the mechanics! There actually is a third level past the second one. The way to solve a level is to collect at least fifty of those mini clouds. In the second level the clouds are quite hidden, if that is the problem. If you are stuck on some kind of obstacle, try every weather state, there should be a way to cross it.
Thank you for playing! I will try to improve the game further, thanks to your feedback.
