I love the character models in this game and enjoyed the comical slap effects, ha. Two main things I'd recommend that hindered me from enjoying the game as much as I could've:
1) Would be really nice to have some invulnerability frames after taking damage. Most games employ this kind of feature and it would've saved some frustration from going from 5 hearts to 2 by hitting one spiked barb on some of the sections with tighter platforming.
2) Would've been cool to see even just one more attack to be able to use. Slapping the eyeballs over and over became a bit mundane to the point that I just started to run away from the enemies on the later levels.
Overall nice job and good luck!
