Excellent game!
It reminds me of the Infectonator games. The pixel art is great, the animations are good too and it even has a boss fight. Very good product considering it was made in a jam!
I read about the bug at the boss fight bug so i wasn't expecting to finish it, but, something else happened too. If the boss lands on top of you, the zombie enters the attack state permanetly and you can't move. Something else to take a look at!
Good work! <3
