Cool game, and really nice work in 48 hours!
I realize security probably not on the top of your feature list in 48 hours, but since I work for a security company doing security assessments it's is one of the first things I think about. I noticed an issue that will let me win without racing.
The reason I bring this up is not, in any way, to diminish your work, but to highlight that you don't get much security for free in these types of frameworks. So this isn't a big deal for this game, but in case somebody was using this for a more sensitive project they may want to be careful.
