- Make the crosshair smaller, just seemed a bit big.
- Take off auto fire, game is too simple with it on, I spent the whole time leaving the mouse in the middle and running in circles just dodging things.
- Instructions could just be after you press start and be very simple with pictures of the buttons, I doubt most people will have clicked instructions then read the text box and clicked next to see how to do the power up move. A simple screen after pressing start would be better for control instruction, (like in Point Blank games).
- Leaderboard, no incentive to be playing through the repetitiveness.
