An interesting challenge

I'll admit to being sceptical when I saw the numerous allusions to Portal, for as good as that series is, the vast majority of games that pay tribute to it do so in a poor manner.
That said, I found this to be an intriguing puzzle game with enough challenge to keep me playing until I finished it. Though the music looped I found that it didn't become annoying, and the voice acting was very well executed - I did find the AI character to be just a little too similar to GLaDOS, though. I will, however, praise your restraint in not parroting 'The Cake is a Lie' (or a facsimile) in the thoroughly annoying fashion that the internet community has on the whole adopted.
Another small complaint I had was the limitation to one use of each of your duplication powers per level, rendering some levels irritating, and I felt needlessly so; in many cases messing up the use of the power would have required a restart of the level anyway, but on the few occasions it did not, I found it a chore to have to redo sections of it just because of a slight mismovement, especially with thesomewhat unstable nature of the characters on the corners of platforms.
I would also have commented negatively on the difficulty curve, as the second to last level seemed to require such unutterably precise execution as to be ludicrous - however, I double checked my solution against the walkthrough after beating the game, and found I had made things far more difficult for myself than the designer intended by finding a slightly different solution!

I'd be interested to see an improved sequel.

I really like what you have done on these levels and they are somewhat difficult to pass. knowledge is power. You got the right idea to make this game happen and have the inspiration of gLaDoS. I will be looking forward to your 2nd game of Invertion 2
