Ok, two things.
One, I've used python for three years now and it's definitely not the best tool for game development. You need multiple plugins to even get graphics to work.
Two, I don't really care if the bossfights game gets popular with youtubers. The main goal for me is just to have a functional video game set in the bossfights universe that people on the stream can play. I don't want it to be marketable or popular.
