Those animal sprites are pretty cute! And the game seems to work pretty well, good job!
In the opening cutscene, the text advanced a little to fast for my taste. I think in general it's better to have a slow auto-advance and let the player advance prematurely when they wish to do so, for example by hitting space.
The levels themselves could maybe use a little polish and sound effects would also be really nice, but assuming this is one of your first games, very well done! Keep it up :)
