Aside from the game not really meeting the requirements set by the game jam, I had a fun time with this one! Having this kind of physics on this game made it interesting, especially the bounciness of the player character. Good stuff!

I calculated the aspect ratio to be 84x56, you had plenty of subpixel movement, the buttons got slightly darker than the two allowed colors when you hover over them... you sadly didn't follow all of the rules. What I can say about the gameplay: the nature of how you're supposed to play, timing your second jump just right, requires the player to either see more ahead in the level than what you show them, or to memorise the level, which is not much fun. You could make it more forgiving by always making the second jump the same height as the first (setting the ball's vertical velocity instead of adding to it) or by showing more of the level ahead (thus increasing reaction time). As it is, you've got pretty much just a memorisation game.

The easy level is hard, hard is impossible, and ultra hard is unplayable. With more easy levels it would be more fun, but the difficulty is really high.

But the first level was fun so good game!
