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 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!

@Elvenghost try scrolling down with your arrow keys :)

Loved it!! More games like this that get you thinking, would like to see more with a longer storyline, the ending was a little predictable, but this is the best game I have played in a couple of years, 5 stars =)


Rated 5 / 5 stars

I really enjoyed this game a lot. However, I must admit I was not the most fond of the ending. One of the best parts of this game for me was that the puzzles felt natural and engaging. They were neither so difficult as to be subject to trial and error, nor were they so easy that at any point I became bored.

A personal note- last year I took a critical thinking course at a local community college. Throughout this game I was constantly reminded of it, and I was glad to see critical thinking mentioned in the after-game splash screens.

Thanks everyone for all your compliments and feedback. I'd love to get a proper programmer onboard and do more with the gameplay concept.

How well it does here will tip the balance on that, but it's edging towards the front page of 'most viewed this week' after just 8 hours, so things are looking positive :-)

the only problem is that when i used the arrow keys it changed ALL of my answers sometimes (Google Chrome)
