Try turning on "Low Resolution Mode" in the app's Get Info panel.

The game stores your files in the same folder as the app itself. So if you're playing it through the Itch Desktop App, click on the Show Local Files button on the right side.
Woo, glad that worked. I've added a note about to the FAQ and I'll also add it to the download page information as well.
The game "should just work" in high-res mode (like the main menu etc)... but clearly I'm doing something that results it it not working in-game. Will keep trying to fix (or at least make it default to low-res mode so players don't have to do it).
