I mean I talked with Daniel several times throughout the development, and he is chill with game being published, but I don't want to do it on Steam specifically because I don't really respect their platform and don't want to pay them $100 for submission. If you know a publisher (or smth like that) willing to help with that, I wouldn't mind working with them (I can suck them off in return :3)
As for online PvP, I'm not really sure. While early on there were some plans to implement it through Discord, it was back when me and Chaosyr were still together and I hoped they would help me with coding. I do have a much better team nowadays, but I am unfortunately the only person in charge of coding. My fangame is already rather unpopular, and there was even less demand for PvP, so I don't want to spend my limited time (and money, to host the server) on a feature almost no one will be using. Sorry to disappoint TwT
