Darnetal, We can help you, I'm sure many of us want this game :3 You had a very original idea, a weight gain tomodachi isn't seen anywhere else
I was thinking of open sourcing the project, actually. I don't have a lot of time to work on it anymore, and since it's supposed to be free anyway there would be no harm in giving public access to a git repo for people to freely participate.
But I still have to think about organization. If I do that, I still want to control that nothing malicious or straying too far from the original idea gets added.
