From the developer:
8BitMMO is a retro-style 2D massively multiplayer game. The entire world is built by players. Build your own house, town, voxelart, or dungeon. The world is massive -- there's plenty of space to build in, and it streams in as you explore (no load screens).
You may want to check out more Mac applications, such as Balls Trial, Varmintz or Insectoid, which might be similar to 8BitMMO.
