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 was an interesting game, took a bit for my brain to start off but once i was underway it was cake up until 9, had to think hard for that one, then on 10 i just freakin quit.
Found the walk-through and finished.
for the sequel i would request no code puzzles but i doubt you would listen.
And i apologize for not reviewing this in the logic puzzle form my brain can unwind puzzles it just can weave them.
This was a fantastic trip and i would love to experience another one perhaps a little long, though i can only imagine how difficult to make these riddles so i will simply await the next.

I've just finished studying Computing at school, so this was very fun to do. I'd love to see how the story continues. From the only objects that were actually in the room, it seemed a bit steampunk. I'd love to see how this continues in a sequel (even if your objective was to show calculus).

Very clever, very twisted and very fun. There was definitely a 'portal' vibe going on with the test subject talk and the slightly off-kilter machine. Too bad we never did escape or find out who we were.
I do wish I had read the summary about the arrow key business ahead of time though, I almost drove myself nuts on the logic problem proving Micheal Atkinson is a douche because I couldn't see half the answers. Is there any way to make that more obvious, or add it into the game/menu screen just as a heads-up to players?
