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

My website:
My narrative design blog, Plot is Gameplay's Bitch:

- 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!



Rated 3.5 / 5 stars

I love the concept, but the drop down menus are terrible, the puzzles often didn't accept perfectly logical arguments that differ slightly from your template.
Also the dialog kinda felt a little condescending by patting you on the back for every frankly, pretty easy logical puzzle you solve.

I'd like to see a more polished version of this with harder puzzles and a better input method. (possibly fields to type in freely using variables predetermined by you?)

Interesting game, but on the easy side and buggy. I got stuck twice, and both times it was because I couldn't see all the options.

The game is awesome. i gave up on level 4, it's hard to get it since it's not my mother-language... It'd be great if it had other languages too, but that would be asking for too much....
