Made it to the win with 1144 points! I liked the visuals, especially the 2 style changes as you progress through the game!
As you mentioned in a previous comment, the jump force takes some getting used to - my experience was that I was confused by how sometimes jumping would seemingly do nothing at all, while other times jumping would splat me onto the ceiling at the speed of light. If I'm correct, jumping adds a flat amount to the player's velocity, while gravity is constantly reducing that velocity? Meaning that If the player jumps twice in quick succession, the second jump has much more of an impact than the first, as it happens at a much higher velocity. Whereas when the player has been falling for a while, jumping does virtually nothing becasue their velocity has been lowered so much by gravity?
If you made a similar concept in the future, I would personally explore how you can make the jump more consistent, maybe by setting minimum and maximum velocities that give the player finer control. It wouldn't have to be 100% consistency with each jump, but as it currently stands the player is quite easily able to kill themselves completely by accident because jumping doesn't behave as they expect.
