I haven't really had the time to test it on other systems, so recommended would be what I have, which is a GTX 1080ti. Did you test it out on your PC?
Works on 1060
I've got an i7 2.2 GHz and I can Play the game which ~4 FPS so unfortunately I can't Play it fluently...
But however, the game is really awesome! Please don't stop working on it!
