That would be a pretty big time investment on my part, and I'm really only interested in making the game I am working on now. Even a short game takes weeks of work, and that would make Goblin Hole take longer to finish. I have an obligation to my subscribers to work on this game. So I don't plan on working on any other games, until I finish this one.
If this is a game you'd really like to see though. I'm sure there are artist online that are looking for commission work, and maybe they'd want to work with you on this idea. I'm gonna be honest though, that's not something I am interested in doing.
