Option 1. No Parkour Mode

Adds ramps to every spot on the map that you need to parkour to get to. This will be good to introduce your friends who have never played Karlson to the game, because they probably suck at parkour. The ramps will only be on their side, so if they think they’re hiding behind a ramp and being all cool, they’re not slick and you don’t see the ramp so you can just shoot them.

Option 2. Milk

Adds milk which spawns around the map. Touching it will heal you to full health, plus 50 bonus HP. It will regenerate every 10 seconds after being used.
