Well done :) PICO-8 integers top out at 32767, so without special tricks that's the highest score it'll display. Looks like yours was 33001. Will be harder in the PC version, we'll top out at 2 billion there ;)
Love the game, man! Hope that didn't come off wrong, I wasn't complaining about the integer overflow. I cannot wait until I have a real PC to download steam and get the real version!
