honestly i never tried this, i just forget that pick up exists until i see a headcrab, then my brain immediately tells me to try to pick up the headcrab

gotta love the source engine.

on the side note your water mark could be a little smaller transparent and placed some where less noticeable. it would make the viewing a little more easier imo. keep posting videos i never would have thought to try to put the pick up items on the tram
