I was inspired by The Science Elf on YouTube creating Minecraft on a calculator so I thought I'd make my own little version for pico-8, it is completely playable using the base pico-8 controls so it does suffer slightly as limited on buttons and didn't want too many complex button combos.
I don't see this as much more than a little time waster game but I hope you enjoy it and I'd love to see any builds made in it. Redstone does work although it most likely will have issues, pistons work too although same deal expect issues.
I did make sure basic circuitry would be doable with the Redstone, so there are Redstone torches exclusively for NOT gates, there should be enough there for some cool logic things such as binary adders but it will probably be a bit annoying to place.
