Two worlds is a game, where you explore worlds. you'll start off in world one, then a while later you'll move on to world two. after world two will come a story... So, if you want to join the collaboration, just remix, change V1 to V2 or whatever, add what you want, yeah. It's...MOBILE?!
A LOT MORE MUSIC! (PS, Credit is in the project. when you start, at the left bottom, It says the music playing.) Sound works. sound starts at 100. if it's at 0, there is no music. $ sign :)
