Back in 2018-2019 I accepted a commission for an animation, which turned into me being a progammer for the game I was animating. The actual creator of the game, Coyotae, was involved with a lot of conflict within his community and Roblox, so his roblox account was banned shortly after publishing the game. Before his ban, I asked him if i may keep a copy of the original game and adjust/remove/change things necessary to make it my own and he gave me permission
I have not spoken to him since 2019 and my question is, if he decides to come back (low chances), and files a dmca report against my game will I still be allowed to publish my version of the game?
