This feels similar to RAGDOLF from last year's jam but with the twist being you have a time limit and you need to hit enemies.
The art and audio is good.
Launching yourself with your hammer didn't feel responsive. I would like a better way to control my direction and velocity.
I don't like how you have overlapped input for attacking, swinging, and launching your character. Often I would try to launch myself over a gap, but hold the mouse button slightly too long and end up doing a hammer multi-attack instead. One button for launch would be ideal. Remove the hold down mechanic completely if you want the player to focus on swinging the hammer to jump.
