Hey, thank you for the feedback! I really appreciate it as I haven't been getting as much critique on the game aside from the UI aspect(s).
This is very insightful feedback as this is actually the very first time I'm making a fighting game, so it's still very clunky, I will admit.
I am planning to add smaller characters to the list and there are some parts of development that have been very difficult to maintain, especially physics and hitboxes. I am currently in the works coding things like gun and pick-up projectiles.
