PS. Thanks for all the positive comments I'm getting. I'm definately planning to make a sequel with tons of new ideas, to continue the story.


Okay, we get It.

This game was fun,and the concept was a unique one, but one thing was constantly annoying me.

Yes, GlaDOS was a fun and Interesting villain, but It's annoying that a lot of these puzzle games keep using the whole "Evil overseer mocks the players attempts to win" to the point where may officially call It a cliche.

But nonetheless, I'm still giving It a nine not because of the robot voice, but because It feels that the gimmick It wasn't used to Its full potential.

(Assuming it's a real person) the voice actress for the A.I. must be really cute, anyways nice game, most levels easy, some tricky, a few RAGE inducing, really reminds me of portal.

It's K.O.L.P.!

It's like a cross between Portal, K.O.L.M. and Enough Plumbers.

...And it is AWESOME. Well done.

Fine art, fine game.
Though too easy and having only 2 challenging levels - rest are more like an introduction to the game. It could have been so much more! And also not really intriguing story. It's like a portal, drawn by child and voiced by him "AND THEN THE BIG EVIL ROBOT SAYS..."
About 50 more challenging levels and it would be a hit.
