That certainly would be ideal, but unfortunately I'm not currently familiar or comfortable enough with binary operations to make it so. Even in its original PICO-8 form it could be taken from 128 bits down to the same 40. I know it's a terrible waste of space as it is now but I never pretended I really knew what I was doing with TIC-80 (or PICO-8 for that matter). Maybe one day it'll be that efficient but even if it's a jumping-off point for someone more skilled then it's done its job.
