Looming Entertaining, indeed.
Almost finished too, but I can't seem to find portals 2, 7 and 8.. and the last secret medal ;) I'll keep looking, bet on it.
I really don't get why some people say it's stupid or thing like that' I'm sure that if they gave it a little time and patience, they would understand what an awesome game it is.
I also like the simple sound effects you put, especially when I go through a portal, it makes me giggle sometimes.
Keep up the good work~!
