Oh really? I'm very sorry to hear that. I just downloaded and ran the file here on itch.io and I'm not seeing any problems on my Windows 10 machine. Which version and build number of Windows are you on (Control Panel > Settings > About)?
7! Ah, yeah, I'm sorry I don't have anything set up to test on anything but my personal rig. If I can figure out a nice way to virtualize older Windows versions and do some light testing, I'll try to do so for the future. I appreciate learning of the issue, but I'm not sure I can offer a Windows 7 solution. I'll ask the Pico8 community for advice, just in case.
