There are various issues like that with the (admittedly dated) engine of the game, which are sadly also not reproducible on all systems. But let me know if the reinstall resolved the issue. Thank you very much!
Reinstalling did resolve the issue. But, I think the actual issue was that saving the game after changing the auto-fullscreen setting caused it to bug out: If that's a problem that can be patched out, great! Also, since I reinstalled the game from the itch.io desktop app, now whenever I click on "check for update", there's no acknowledgement that an update check was made. I think that has more to do with the app itself than the game's installation. So, I'll try as clean a reinstall as possible to see if that resolves this newfound issue. UPDATE: I can't uninstall the game from the itch.io desktop app. So if any updates come in, I might not receive them. Sorry if I'm causing so many problems for you.
