So basically I am trying to find that old game where you get to customize your avatar and they give you an option where you have to choose either a Mecha leg or a rocket booster as your leg, and there are options where you can visit people's buildings and interact with other people just like in Roblox, and there are like these things where you have the ability to place boosts and other stuff that I can barely remember, if anyone plays or remembered that game, please help me out
