I guess sometimes it's inevitable to upload an unfinished game into a game jam... This is much shorter that what I had expected though. It's only the intro stage but it's surprisingly not bad. It seems you prioritized polishing over length; and I suppose an unfinished but polished game is better than a full-content but totally unpolished game.
I think this is pretty standard though (although the hold any key mechanics is pretty creative) and can have some more creativity - but hey I have nothing against something standard. Not bad.
Good job, and good luck!
