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!

this game was pretty sweet, id love to see more of it, ive been thinking about (and intrested in) philosophy for abit and this just made me want to learn more xD, i got stuck on a few of the puzzles and i was confused on the door but passed it without failing once (shocked myself lol).
all in all i found the story great to (funny as well) so i rate it at the max :)

Great stuff, I did a couple of logic courses at uni so it wasn't too tricky but it was nice to have the refresher.
Nice art and the sound is decent.

This is, undoubtedly, a god tier game. Because of this game I will begin using logic more throughout my days. I am doing it right now, by stating facts in short sentences. You have done well in the construction of this game. A sequel would be appreciated.

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