Well, somehow one folder name got messed up, but that was easy to fix. (Don't change names after the project has been built.) You already mentioned that you wanted to add a few more things, but they also don't really seem to make good use of the duel movement you designed. I could easily play the game only looking at the right character, only checking to see if the platform also existed on the other side.

But non the less, it is a good result for your first game jam (mine wasn't much worse), and I hope you can use your experience the next time.
