absolutely love the art! Found myself wanting to play more levels than available, but one thing that I did feel a little spun by -- as far as I could tell, the perma-fly buff didnt seem to let me do anything different (was expecting maybe I could fly over gaps for instance?) It also made me wonder if maybe I could normally do a single gap and the flying let me do multiple (which also could not, as far as I could tell)
Great work, and I might just have to play a few more times -- even the upgrade icons are too cute ! :)
