Yea, maybe now I can agree with our argument related to controls, just thought I will be cool idea to have such controls.
But now I think that it would be better to stick with default bullet hell controls.
Looking at enemies, that you mean by "Enemies don't move much", they move to slowly, or just it is very easy to avoid them ? I had some problems with delta time and velocity physics in general, had a hard time to implement proper enemy movement. Well If speed is ok, I think it would be better to just add more patterns to enemy movement.
