Great. Next time give us more gameplay :)
The controls could have been much worse, but what you gave us here is not perfect either...
The cursor movement/turn ratios definitely needs more tweaking. I am finding myself doing much too effort to just turn from side to side, and the "strafe" movement it too minimal, as well.
I wonder now if an old-school keyboard-only approach combined with a high frame rate would make this game more fun to control.
Great job with the graphics . I was amazed to see all kinds of detail like the menus and the bullet impact effects that looked great (I just sat there, shooting at the ceiling)
Also, definitely improve the enemy's A.I even if by a tiny bit... for example make them stop walking towards you and maybe move sideways a little bit, or shoot at you, or just stop in place for a second and scream bloody gore at the player. Shouldn't be hard to implement.
Very impressive engine! this has future! I wonder what it'll be like for 3D genres that have simpler controls.
