but it wasn't so challenging
if you walk to much the arrow keys are not working portals don't work too(great idea in fact)
Awesome game, but...
I'll give it an 8 because I could not reach the last stage...
There's a bug when I try to finish the stage 39!!!
Everytime I try to pass trought the exit door, I come again to the entry door!!
you can gap the glass, but cant jump onto the electric field.
GOOD, but flawed.
I found PORTAL a very fun and chalenging game that almost brings the level of fun and enjoyment as its Xbox360 relative.
Although fun, it quickly turns into a big energy ball of frustration when nearing the end.
I am not talking about the levels or the gameplay.
Apon entering Lv. 30+, I started noticing some VERY BAD glitches.
One level I would be trying to get to a higher platform, via infinite loop.
when all of the sudden my character would suddenly vanish out of thin air only to reapear infront of an active turret. from levels 30 and up, they were very painfull and very VERY frustrating. I dont know if this is a reoccuring problem or what, but consider revising the last few levels. other than that good game.
