Are you a protogen in this game? :) It's adorable. I love the lil' running animation of the protogen, as well as the enemies' animations.
Speaking of which, it was pretty fun to see all the different kinds of enemies there are. Good job on completing the game.
Something I would change is that, at times, there's a lot going on on the screen and it's hard to tell what is what. Maybe you can make more visual distinction between the enemies and the background too, for example.
