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

Feel free to host the game on your site.
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.


It's not bad

I've played some seriously shitty games... and this is not one of them. But I don't find that I want to recommend this to anyone. It's not entirely compelling.
The music is good, and the graphics are decent. The voice-acting was well excecuted, but the script is lacking.
This game doesn't seem to find it's home in any category other than tribute, really. It's not strong as a platformer, and it's not challenging as a puzzle game. I would recommend concentrating more on one of those aspects, and fully fleshing it out before you call the job done.
Don't be afraid to beta-test.

Infinite lives are great for puzzle games, but they turn platforming into patterned button-mashing.
In no way is this game bad; but I don't find it to be fun. It doesn't push me to think differently, or challenge me.
At least it's intuitive, I find. You've done a good job, just not a great job.

PS the only reson im giving this a 1, is beacuase the voices where pretty good.
but that's it!

P.P.S. I would rather you have not so blatantly copied Portal, but following ValvE seems to be the way to go for games these days... So I can't really blame you for that, and it doesn't detract from the game.
Good luck, and I'll see you in the sequel!

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.'

its OK fun but its stupid once you begin but when you start to play its fun

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

Its good

Its pretty good. But there are problems.
One, its looks and sounds like Portal, with out the portal. Not a big fan of copying
Two, the scrip is kind of boring, although it is clever at times.
Three, and the biggest problem, is the controls are not very responsive. I keep running into, not sure, maybe lag? When I press up to jump, my little robot minion does NOT jump. Yes I tested this extensivly as you can while only pressing one button. No, its not me.
Anyhow, all in all good game. I hope to see another. Just work on the story and game mechaincs a bit and you'll be gold
