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!

I feel like such an idiot, that I'm crying.

I don't get any of these, and I feel so stupid.

I haven't come across a game as original as this one in quite a while! It was perfect, except for the fact that the last puzzle (number 10) is crazily-hard. I was only able to solve it when I started messing around with the arrow-keys and I saw the right answer.

You should definitely make a sequel to Ir/rational Redux, but I'd strongly encourage you to use a different type of drop-down menu, if that's possible, one where answers aren't occasionally hidden.

I promise, I will never use drop downs again. Believe me.
