Not the most easy thing to create an endless runner for a jam, congrats for that!
The gameplay feels a bit unfair, so I wasn't able to reach the golden ratio (5:1).
Unfair because:
- jump is a bit "robotic" : not easy to know where you will be landing
- when you jump, it's like all the screen "jumping" but not at the same speed, so it gets blurry and gives headaches
- when you've got enough orbs, the choice offered is often between jumps, which will often lead to your demise
Anyway, I think the concept of reshaping the world is an interesting one, maybe doing it collectively could help this theme shine in your game?
