Have fun!

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.


Not a bad game at all

The game was fun, and the robots were cute, just getting a little tired of Glados being inserted into every game.

Less than the average

-1 The woman doing the role of Glados did a terrible job
-1 The controls are too slippery, i feel like i'm in an ice stage of a game, during ALL the game
-1 The stages were all too easy, without increase in difficulty
-1 This "illusion" mechanic is over-saturated, as well as that "sad robot" theme

Game Glitch

When i get to the room that introduces that you can 'R'estart, i try to press 'space' so i can go through the door but it does nothing when the lazer is down and toggles off the lazer when the lazer is on. I think the dialogue is somewhat uninspired, but i was at least enjoying this game until i got to a part that had no solution. (even checked the walkthrough which was unhelpful.)

i like it anyway

i also think its a ripoff of portal but stil ... great game anyway


Horray for Portal rip-off! I am sorry if I am a little harsh, but you can't just do a puzzle game with a mean female I.A. and hope it's good. Still good idea but for me it's just not there.
