Love the stylistic lizard noir!
I also really like that one of the enemy types is a turtle on a skateboard. :D
The combat does need some polishing, enemies will slowly drift away while beating on you, and start punching the air for a bit before re-orientating on the player. Getting stun locked is sort of a given for side scrolling beat-em-ups but can still feel frustrating when every action the player tries to take gets interrupted. The turtles sometimes skate off screen and leave the player stuck, waiting for them to come back and fight before they can progress.
The right-click charge attack is massively over powered, you can win every fight simply by holding down the button and sweeping up the enemies in your deadly whirlwind. A time limit on that would probably be a good idea going forward. :)
Sound effects for hitting/defeating enemies is also, of course, vital to a game like this.
