Congratulations on your first jam! Good job!
The game is hard fun and the design is very interesting. It is satisfying to improve skills by repeatedly trying. I feel I'm a PRO platformer now!
Haven't figure out how to hold on the the sticky circles. I think it says pressing A or E.
Also found that jumping from edges maybe ignored sometimes.
I don't know if it's possible, but if there are some checkpoints player may could be more encouraged to reach the end.
