Is that screenshot from the itch app, or the website? I tested the Itch App on my machine and was surprised how smoothly it worked, it's a lot like Steam. Download App - itch.io If you have already tried both the app and a direct download from the website, it's definitely the security/permissions on your PC. : ( Unfortunately, making a Steam page for this game would cost $100, which I just don't have the budget for right now. I may upload my free games to Steam for people to enjoy in the future though, once I can afford it.
