Downloaded both versions about a month ago, and neither will run... they'll get about as far as the loading/logging in screen, make the custom cursor show up, and if I'm lucky they'll get to a black screen afterwards with some ambience(?). But after that? Trying to do pretty much anything, full screen or windowed? Either I'm forced to force quit through task manager because it won't respond, or I'm prompted to close it by Windows because the program isn't responding. No from-game error messages popped up to give me a lead as to why it does this. A real shame, because this game seems so neat! I'd only hope that if I can ever get it running, that it doesn't lag (as many larger or more ambitious Unity games-- even low-poly ones-- do on my weak little old computer... but at least they get past the first screen and attempt to stutter forth).
Attempted to run both versions available to download on a 64bit HP Windows 10 PC that hasn't been optimized as a fancy gaming PC. Neither was playable, I don't know if it's a hardware incompatibility issue or what. Haven't tried the Steam version, got these in a bundle.
