I really liked the game so please don't take what I'm about to say the wrong way. It's the little things that would've been great to see on this game. For example "Press P to pause" so I don't aim away from the enemies. Being able to lower quality (usually pressing Q) would help with the lag issues. Being able to mute music and keep sound effects is a great feature for people that like to play with their own music. Again, minor details that would've put this game over the top for me.
