Am I missing something with the faster version? I loaded both versions onto my Playdate, and the fast version runs identically to the slow version. It's not faster at all.
Faster version runs at 50 fps instead of 30 fps of the normal version. I do not own the real device yet so I only can test with the device emulator. Other players with real devices experimented a little game speed up with fast version. Best regards.
On a real device, it is definitely not faster unfortunately. It's still a nice little take on Pac-Man for the Playdate, but I can confirm that the fast version runs identically to the normal version on a real device.
