Very ambitious project, and the idea is really interesting. Unfortunately, though, it freezes quite a bit when I try to play it. Maybe it would run better as a downloadable version instead of running in the browser.
I updated the package to a new build that only fixes the performance issue and main bugs so the game is actually playable for testers. I'm stretching even more the 3 hours rule with this update but the end goal is to a have fun here.
