There is a tool tip explaining how to add a character to the game but it's very easy to miss, it took me a while to notice it. If you get ahead in the game it's hard to fall back behind and it's hard to win once you are behind. One of the levels had an obstacle that just killed you which wasn't fun because I died early and was forced to wait since there is no respawn. It's easy to fly off the screen which makes it a bit confusing. The clouds being obstacles are a little annoying, The game is very simple and gets boring quickly but the art is adorable!
