Would it be possible for this game to get a multiplayer feature like Minecraft does, where it's pretty much the exact same game except now there' two or three people playing instead of one.
The only real reason I could think of not to do this was because of the time control thing, but that could just be taken out for the multiplayer version. Singleplayer let's you control the time to easy up the boring parts, or give you time to think, then when you're playing with your friends you have to play real time.
I think it would be fun.
