I don't think I've ever heard of "reverse roguelike" before, interesting. I was getting into it and I actually did manage to beat the boss by just shooting it run & gun style and that was fun. Though the V and F keys didn't seem to do anything (I think the F key would occasionally do a punch, but it didn't seem consistent), and I couldn't really do anything to the smaller characters there either. The 3D art aspect of the game was pretty slick though! With some tweaking and balancing and just better responsiveness, this could definitely be thing though. Solid work!
