Is cart-save support planned? Would be nice to have progress saved when powering off.
I'm not planning any save system right now, my focus is to fit as much things as possible in a 32 kB cartridge (that's the "challenge" I set myself originally, and it helps me to avoid adding too much features). Since there's no save, every level is already unlocked when booting up the game and progress only affects cosmetics. (Also, I have to say that I haven't looked yet at banking or saves at all, but it may come with future projects!)
