Thanks for playing the game. I really appreciate the detailed feedback, I feel like people usually avoid being too direct on game jams so sometimes you don't get the critique you need.
I didn't experience the issue you had with jumping. I thought in that way the controls were fine. Not sure how I could fix them in that case either. Maybe reducing the jump impulse(how much force is applied initially), but also reducing the downward gravity acceleration a bit?
For everything else I completely agree with you, most of them were issues I was aware to some degree during the work. I think it boils down to what you said, it was overscoped. I need more experience working with some core mechanics for these types of games before I could execute it properly in such a time frame.
