I'm sorry you lost so much work, but funny thing is even though the final result is a small game it still has great Gameplay, Presentation and Originality and, as such, may win the jam yet. I had played the web version and although there was a tiny bit of lag it ran just fine after the first room. I rated your game (gameplay 4/5, presentation 5/5, originality 3/5) and I enjoyed playing it. Great work!
