Alright so I'm apparently having miserable luck with Unity WebGL games; it's just not recognising any input at all (this isn't the only jam game that's having this issue so it's probably Unity's fault :|)
Could you put up a windows build?
I see. I'll consider Windows build.
Thanks!
From poking around a bit, this bug doesn't affect older WebGL games, so it's probably an issue with Unity's latest WebGL player. Fun :'|b.
