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

- 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!


Just, this.
I LOVE it.
This is one of the most original things I've played in a while. It was really well done. The way you did the hints was good. The very last puzzle was a beech, and I'm still not sure if I entirely get why it worked, but this is still an epic game. I want MORE.
1. I like this game.
2. IF I like this game, I should give it a five out of five.
3. THEREFORE I will give this game a five out of five.

Very well done! The screens, music, and the narrative set the dark mood. The puzzles (for once) made me think very hard. Also the Dark humor relieves just enough tension to let your guard down to what could happen.

Great idea, good puzzles. However puzzle 10 is just... no. There was no symbol there to represent "IF" in the key. There was also a symbol of an arrow going in both directions that wasn't even in the key. Generally puzzle 10 made absolutely no sense at all to me, and I'm pretty good at puzzles in my opinion. I love the concept but something like puzzle 10 should just be avoided.

What a sick, twisted, glorious, amazing, worth-while game. It was fantastic. I look forward to more things similar to this.

Logical arguments never move past simple, while I had never experienced some elements in the game it was still easy enough for me to never get one wrong, which was disappointing, don't get me wrong this game is both original in content and really fascinating to play, but I wish the story continued with some reall REALLY brutal stuff. Perhaps in a sequel. Thanks for the great game!
