Good stuff! Got here just a few notes:
Since I'm using an Xbox Oone controller, it's pretty awkward that B is jump and A is to fire, if there was an option to swap those that would be great!
This is more of a personal thing, but 1 hit kills feels a bit too hardcore, maybe 3 hits would be better? Or you could keep 1 hit kills but have a certain number of continues.
The game is solid though, and I really love the designs for the enemies, especially the tacos!
