Ok, I made some more changes:

- FIXED THE MENU. (it should no longer screw up your firing)

- There are 2 difficulty settings now. (Normal and Hard)

- The red thing that appeared when you stood still now has a button that can be used to turn it on and off permanently.

- Made the red thing look better. (3 instead of 4 points that now move in and out as well as round in circles)

- I also changed the way weapons are equipped from your inventory.

drone also got a review at:

GMC review

Not the most positive review, but all feedback helps :D
