UPDATE 2: Walkthrough available here: http://blog.tomjubert.com /2012/07/irrational-walkt hrough.html

UPDATE 1: Made 10,000 views and the Popular Games list in 24 hours! Thanks to everyone who's played!

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!

I simply adored this game. It's originality was backed up by the fact that it was fun as hell to solve through this game. I do hope you are planning to create another game with the same rational thought element. I saw no problems with this, well deserved front page.

Which is more important to the game - the philosophical setting, or the logic puzzles?

Can't zoom out, can't play the game. Please fix right click, it's a pain in the ass to not see the whole words.

It's such a great shame for me that I cheated on particular levels...I'm such a irrational human being :(

This game is pretty freaking awesome. I like the idea of logic being the gameplay. The music is freaky and creepy, which fits the theme. Also, marmite is best with cheese xD

The game was great. The scarry theme in the whole process, the logic riddles - I just love them! (sorry for my bad english)
The hardest, as always, was the last one(10). I spent 30 min, trying to remember the logic formulas, for the code.

BTW, what is the REAL ending in this game?*you haven't shown the conclusion, or you are gonna take it to the sequel(can be great)?*

PS: My brain is still spinin' like a dynamo machine!)))))

Thanks!

You saw the real ending. I'd like to do more with the concept, but I don't know that I'd continue this particular story.
