Hey, it's a bit too late for me to make a demo, and I don't know how it will run on your PC. But I can give you this tip: by default this game has a super rough, retro, pixelated art style. So in the settings you can turn down the resolution to a very, very low level, and with full-screen it won't have much of an effect on the look of the game (but could increase your PC's performance a lot.)
