Some small tweaks

I mostly did stuff that you will barely notice

• You can now reload your gun by pressing “R”
• Made a small tweak to the scoring system. It is now easier to get a higher score
• Added an extra fullscreen option
• Fixed a bug where if cancel was clicked in the settings menu, the changes were saved but not applied
• Added a new gun system, so I can easily make new guns
• Dark overlay when you die
• Every 20 seconds, a new gun drops in the background of the title screen
• Changed magazine size to 20
• Added a shooting cooldown of 0.1 seconds

The ratio of the amount of shots you hit and the amount of shots you missed is counted for the final score. When you hit a turret, it will sometimes count as a missed shot and sometimes count as nothing. I did this, because shooting turrets is not the focus of the game.

Edit:
Forgot to say

• You can drop your gun by pressing "Q"
• To pick it back up, look at it and press "E"
