Hi, welcome to game jams world!
As mentioned before it seems that a file is missing to start the game.
Good luck!

Really nice! Good and simple art, simple but effective gameplay. Good implementation of the pause mechanic, with a few interesting uses.
It was missing some sounds, but mostly some improvement on the hitboxes / movement and some feedback, it appeared that I died once or twice when I though I was far from the spikes. I got stuck in the environment sometimes.
A good job overall! Next one will be even better I am sure.
