Using Baba Is You to practice game development is a totally healthy hobby
I welcome you to take my ideas and put your own creative spin on them, and you're also 100% welcome to use my original music (so long as you credit me, of course)! You're also encouraged to make videos on everything here if you'd like to, I love watching people's reactions!
If you want to chat... I don't really have a great email for that or anything BUT I'm fairly active on the Baba Is You discord server, so feel free to reach out to me there :)
Small, varied levelpacks about Baba characters getting into legal(?) trouble!
