Graphically very cool. I like the style. The gameplay concept somewhat works, though I think the feel is a bit messy. Starting so high is a bit frantic. Jumping is consistently high and could really use some vertical control. The overall pace is somewhat fast and hard to keep up with, like I'm never sure where the next jump will land. The keyboard control layout is not ideal either.
I'll also mention that Godot buttons do take mouse inputs by default, thus your menus can be clicked on.
I think there's some improvements to be made but good push!
