OP I'm building a very extensive expansion mod for this game. I have no idea how to directly contact someone on Itch, I just now made this account to tell you about it.
I retaught myself C# and Unity for this. Your game is better than Isaac and I kind of got obsessed. I'm not sure I should upload it without your permission, so I wanted to hit you up before I do anything like that.
It's almost done, so, it will definetly see the light of day eventually, just a question of finding a few more days for spritework. You interested in seeing it?
