I have only 2 things that I think would make the game better,
1st, allowing the player to dash after they hit the ground from a slam, so impact animation cancel, currently you need to wait for the animation to be finished it doesn't feel super great.
2nd, making shift sprint instead of space, that way you just have a line of the 4 inputs, space can be interact or something else, but Shift as sprint seems like a better option
other than that, game is great
