How to add other people in

I want to let some of my friends be able to completely edit my game I want to get their edits saved is there anyway to do it btw we all have different accounts.

Allowing other people to edit your game is not possible, yet.

Grazer (the creator of flowlab) is planning to implement that. You can read about it here.

For the time being, if you trust your friends you could share your account. Or if you haven’t made the game yet you can create a new flowlab account for you and your friends, and create the game there.
