-- Reduced setup time from 15s to 10s
-- Scoring a goal now adds 45 seconds to the timer
-- Updated the func_clip_vphysics brushes with a filter-- now they only block pipeballs (as intended) instead of all physics objects, such as projectiles and ragdolls
-- Replaced several sounds with their PassTime equivalent
-- Added an explosion and particle effect when the winning goal is made
-- Drastically reduced the phys_pushscale increase, from 30 to 12.5
-- Added "Goal!" popups for each team
-- All goal icons are now 'locked'

PIPEBALLS
