i remember that aaa
i wonder what it was
kind of hard to explain
it's a little fuzzy, but it was a perlin noise-generated cubescape with low-level infinite water. in order to build, you had to place a "building zone" and you could only place one. there were crops you could grow and harvest, when you harvested them you could plant them as bricks to store them so they wouldn't take up your inventory. there was also a mine that was randomly generated that you entered through a teledoor. you progressed through different teledoors and mined for different things, and there was a chance that there would be a cave-in which meant you had to
GET OUT OF THERE NOW. once a cave-in happened the cave would be reset.
there was also currency. you could also kill each other iirc and you'd drop your stuff if you died. you could also steal each other's stored, harvested crops - though i'm pretty sure that was a bug.
