Argue the toss in a twisted tale of logic...

In ir/rational you complete, create and discredit arguments by selecting propositions and filling in the blanks. It's a puzzle game based on propositional logic, and a graphic adventure all in one - only here you don't so much need to escape the room as prove why you'd even want to.

- Unique, language-based argument system: formulate logical proofs to progress through the game

- Dark philosophical comedy by Tom Jubert, writer of Penumbra, Driver: San Francisco and FTL.

- 10 screens and roughly half an hour of intelligent, challenging and inventive gameplay

- Musical score by award-winning composer Mikko Tarmia

Instructions:
- Click to progress story
- Complete the arguments by selecting options from the drop-down menus

NB Some systems don't display all the dropdown options at once, and you have to use the arrow keys to scroll.

If you can't see the right answer, chances are you can resolve the problem with the arrow keys. Hope it's not dampened your enthusiasm!

IF everybody is different, then nobody is special.
THEREFORE: IF nobody is special, I am not special.
IF everybody finishing this game got different rational potential realization rate, THEN everybody is special.
ASSUMPTION: Creator of this game did NOT design and code this game to be complicated enough for everyone to get different rational potential realization rate based on accuracy and speed of decisions during the game.
THEREFORE: Everybody finishing this game did NOT get different rational potential realization rate.
THEREFORE: Everybody is NOT different.
THEREFORE: Nobody is NOT special.
THEREFORE: I am special.

(Alternative ending: If you start with the claim that everybody is special, not only you come to realization that everybody is not special, you also cannot logically prove you being special. This game plays you as you play it.)

I definitely liked this game. I've never played game like this, advancing by making rational (and irrational) decisions, using logic.
As you can see, it inspired me to continue logical thinking by making full arguments.

It's not really a complaint, but it's a shame that this doesn't seem to have much replay-value. Still, definitely gonna bookmark this, and recommend to my friends.

Really easy until the last step, when it falls in a loophole with no meaning whatsoever.
At least semantically and it is impossible to get out of it apart trial-and-error.
Fix this logical fallacy and you'll get 5 stars.
For now only 1 because it is unacceptable to see a logic-based-game fall on things like this.

This was a very nice game, definitely made you think. If you made another game of this genre, I really wouldn't complain.
