Paint the Town Red: Restaurant on the forest road (Warlock Mode) 

Custom Map: Physical Damage ("Experimental")
Creator: ApcMax
"Experimental" level
The whole point of this level is to use the "custom physical prop" bug.
The "Custom Physical Prop" bug is a bug where you group props/primitives with physical props.
Using this bug is a crime and can ruin your level, so I don't recommend using this bug, it's better to wait until the developers fix it and add it as a feature.
