Completely changed the spawning system, now you have to go into a menu to spawn things by pressing Z
Added a new weapon : M1 Garand
Added seven new items: Chair, Table, Bed, Box, M1 Garand, M1 Garand Ammo, and a jet AI.
Changed the pausing system, now it doesn’t take away your equipped weapon when pausing, an enemy will still attack you after you unpause, and pausing now stops time.
Changed the sound on the pistol
Increased the fire rate on the pistol
Increased the fire rate of the AK47
Added a spawnable jet AI

Note:
Now that I have (almost) completed the spawn menu, it will be a lot easier to add new object, so expect a lot more items in the coming updates.
