Until I played and beat the Xbox 360 version of Portal I had no idea what to do in this game. Now it's so much easier. Nice game. Not as good as the console one, but that's expected on newgrounds.
good real fun and a little challenging but after playing the real version it looks like a ant next to a giant and you should put the robots voice there too :) (did u asked valve to do this ^^)
This is pretty epic.
awsome but lags
The irony here is that Portal is easier than this.
Took me a few hours to beat this, but Portal went in about 2.
