I wish that there was like a meter to let you know when the jump was going to happen also some air steering maybe? Other than that the concept is super cute and I found the challenge enjoyable.
I wanted to have the player flashing blue faster and faster to signal a jump was coming. But didn't have time to implement it. Like the idea of a cold meter though! I did think about adding air steering but also felt that went against the theme of the jam a bit...
