i purchased hl2 portal the day it came out.... while loads of fun, it was way too short.... this mod has extended my enjoyment of this new gameplay concept.... THANK YOU! i hope you guys continue to patch and add new levels.... (set up a paypal acct and ill be happy to donate so you guys have some kind of incentive to keep working/expanding on it etc) maybe some new/other gameplay modes? ANYWAYS, THANKS AGAIN! keep up the good work.
