I definitely wanted to make the AI more sophisticated and modular, but at some point it in development it just got to that "good enough" point and I had other things to do so it stayed there hahaha. Definitely a tricky thing to develop for me personally. the game was definitely designed around a controller and I think we could have done a better job (any job) teaching and explaining the controls. The various difficulties are just increased damage scaling on the enemies, 1x, 1.75x and 2.5x. I like hard personally! :D
Thanks for playing and for all the feedback!
