Using the stages of a butterfly as actual levels and having the ending of one level be the beginning of the next stage? Now THAT's a creative use of this theme!
The graphics, soundtrack and sound effects were sublime throughout and each level had solid controls!
The only real critique I can give this game is that I don't know if I just have a skill issue, but it felt like the butterfly was a bit too slow. Once the eagle came on screen, if you were in the middle of its path, you were done. I feel like the butterfly could've been made a bit faster, or the eagle hitbox smaller, but maybe that's just me.
Overall, pretty awesome game!
