Gamepad support? Instant high marks from me, haha!
As others have said, the difficulty is a little here and there, though with the gamepad it makes way more sense. Still, that final boss' machine gun is a little hard to doge. Really, I think a lot of it is more finessing than major changes.
Using Godot engine? More high marks! I love its audio implementation. I can't wait until we get better 3d audio implementation, though. Still, it's getting better all the time!
I like the idea, magical girl plus gritty realism. That soundtrack would be all over the place. Ina good way, haha! Lots of fun. Wish there was more.
