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!

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!)))))

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.

Interesting game, but I cannot finish it due to the dropdown list bugs!

I'm in level 7 about Australia video games. First I was totally confused, I only saw the first 6 options of every dropdown and thought those were really the only ones provided.

Then I read your comment in NG saying that you need to use arrows in the dropdowns. That is already not normal: normally dropdowns have a scrollbar in that case.

But then, if I press the arrow key, all 4 dropdowns change their option at the same time to the new one! That makes it impossible to complete the game.

Please fix those dropdowns dude! I'm pretty sure Flash must support better dropdowns. Try to figure out what the bug in your code is and fix it? Thanks!

I really like the design of the game, so it's a shame I can't give more stars...

tjubert responds:

Sadly this isn't a flash thing - it's a crappy feature of the drag and drop package I'm using. No way that I know to fix it.

Last night I used rational thinking to prove that rational thinking is irrational (in certain situations). Fortunately for the sake of humanity, I've forgotten.
Sequel? :3

Cool concept! The game had me thinking for quite a while but perhaps a little bit more challenging would be better as people tends to get lucky when multiple choices are presented.
