Invertion is a challenging puzzle platformer game. You'll need all your skills to finish this Portal inspired adventure.

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.



Rated 4 / 5 stars

Pretty good.

I don't know why everyone is bitching about it being a 'Portal ripoff' like they've made the discovery of the century. It says right in the description that it's a 'Portal inspired adventure.'

Portal 2 Ripoff

C'mon, I've not played Portal and recognize that :P

BUT, it was still fun and amusing (for the time that it amused me anyway).


Rated 4.5 / 5 stars

why bad?

not sure if troll or just stupid
cmon, it deserves front page

i dont think it's absurdly hard, well, at least i dont need to optimize distance like doing math

just one complaint/design issue:
i thought the Z,X keys mean mirror at first, which can be used once only ,
if you think in this way, the second last level may bug you,
on that lvl,it seems that there's no way but to use X twice, yes twice.
it's not split/mirror,it's duplicate, you have two clones, each clone has one clone.

Intense puzzle platforming

Wow! What a trip. The mechanics of the game are amazing, and the level designs are pretty good, too. I only have one dismay, and that's that in order to beat the last few levels, your platforming skills have to be right on. I don't like when a puzzle game requires such perfect movement. I'm not even sure if I did the second-to-last level right, because for some reason, I was able to vertically split for a second time.

Good game. I enjoyed the voiceover, graphics, and all that stuff. I hope to see a sequel.

Rip off of Portal

Could have been better if elements of Portal weren't so obvious
