I was able to see this project during the initial prototyping stages, so it's awesome to see all the improvements that have been made. It's similar to QWOP while not being an exact copy which is good. The 3D assets blend in well with the 2D, making the overall appearance seamless. The music and response menu screens are icing on the cake too!
You already have polished gameplay, UI, and title screens. I recommend adding a tutorial portion stating the game's controls as it's not obvious unless you were to be looking at the itch page.
