Very cool sprite work! Jump collision was a bit weird, and the player's attacks come out way too slow to actually kill anything.
Some suggestions:
- Before voting ends, try to patch it with a "bugfix" so the attack animation is faster, like less than 1/10th of a second
- Before you make your next platformer for a game jam, watch some youtube tutorials on things like platformer controls, animation, and coyote time.
Good luck with your game dev progress!
