Patch 1.5.6

Changelog:

• Added a cheesy Story Progression screen after completing the last level of each episode
• Added a Brightness slider in the Settings menu
• Fixed weapon muzzle flash and lights that got stuck when switching between weapons quickly
• Tried to fix some map exploits where you could easily bypass level progression

The Brightness slider was a weird one. Unity has no internal way to change the screen's brightness/gamma, so I had to get creative. You are able to change the brightness value ranging from -1 to 1, zero being the default value the game has always had. This doesn't affect UI elements, only actual gameplay.

Thanks for playing guys!
