Ahhh, hadn't even considered that it's totally filling the single player fighting game niche haha! Good point there.
I'd honestly be offended if you'd managed to make it non-buggy within a game jam. If there's any chance, though, of you finding the time/motivation to add one single thing to this version, I think any kind of save feature would be huge. I mean being able to come back to the game without losing your unlocked moves would instantly make it waaay more replayable.
Idk... just like a lil string in window.localStorage? Not that I know what I'm doing. It would just be awesome to see it without having to wait for a full version of the game, however fragile of a save it might be. I understand if it's not in the cards though :)
