This Mac version forgets high scores. I tested, and high scores are saved to beltrunner.save.json, but then the file is reset to default values every time the app starts.
I like the other changes. The new splits moving during stop-time feels good.
New builds coming in the next day or so, these will add persistent high score saving across all platforms (Dreamcast via VMU, etc). Plus! Even smaller distribution zips.
