I know about it, though I have no idea what caused the freezing issue. I could release a Windows version which should be much more stable. The windows one is actually the one I originally worked on.. I only had a few minutes left to tweak the code and test the web version when I realized I was working on the wrong build, that's why it turned out so..glitchy. I'll try to smooth it out after the jam.
About next year... I hope I will be able to do game development more often, to learn more and make better games, maybe go into it full time at one point..:)
