Very nice platformer game, with nice visuals.
Unfortunately, the game was very frustrating at some point, because you simply didn't make any progress and the checkpoint was very far away. Don't get me wrong, i love hard games. But you need to balance the game in order that it doesn't feel unfair. However balancing in a 72 hour game jam is very difficult, i know that, time is a bitch.
Apart from that, i think the controls are very smooth and i love the wall jumps. Good job.
