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

Non-exclusive licenses are available.

Just contact us.

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

Even though obviously inspired by Portal, this game has enough differences to make it truly a good flash game.
