Thank you for reporting this issue!
Based on how the screen is cropped, would you happen to have changed your Windows Display Scaling option on your computer (Or equivalent for your operating system)? Also if you installed the version on Steam, are you able to navigate to the options menu and change the resolutions setting there to any avail?
In the meanwhile I just updated the Itch.io version here with a patch that might fix the issue. Please let me know if it happens to fix it!
