Your Linux build only includes a 32-bit (x86) build, so I can't play it! Can you provide an x86_64 (64-bit) build?
I should be able to! Let me sort out a build & throw it at a tester tomorrow to make sure that nothing breaks and I'll get back to you when it's live :D
Does buying this using itch.io give me the 64bit linux version (if there's indeed one)? Thanks! (I think Linux distros are to the point where distributing 32bit apps is a hassle for more users than those few that still run 32bit hardware)
