Awesome
I must say I'm pleased you added sounds, as soon as I started playing I cracked a huge grin at the loop, its totally OLSCOO!!!
Game is as great as ever, addictive as heroin, more original than 98% of the other portal games,and just god damn fun to play.
Still have trouble with bleeding eyes due to those thin tunnel edges, but you get used to it (and I know it can't be fixed).
Great difficulty on the game, poses a decent challenge the first time round, then a greater one in the form of topping your previous score. Theres notmuch more I can say that I havn't said already on the BBS. Just brilliant stuff, anyone who doesnt appreciate this game (3.45 WTF!?) is simply a fool.
Good luck with the next 8 games.
