Glad you liked the game! Actually working on a sequel to Slipways (another PICO-8 game of mine), so PoC will have to wait its turn :)
Wow! Two sequels! :D What will you add to them? How much will you be able to add since Pico-8 only has 256,000 bits to work with?
Sleepways is cool. It would work great on a screen bigger than PICO8.
