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 4.5 / 5 stars

this is a great game and the difficulty seemed just right for most of the puzzles, although the red herring puzzle seemed a little to confusing.


Rated 4.5 / 5 stars

Very nice game. The ending was not completely satisfying, but adequate enough for a game of this proportion.

My playtime was somwhere in the range of 5-10 minutes, All puzzles were correct at the first attempt. Most time was spent reading the story (which was very nice). However, I teach Logic & Set Theory so I would advise you to not take my time into account.


Rated 5 / 5 stars

Despite the ending the puzzles were worth the time, despite the last one being mind boggling to me at all times. The ending was a bit of a let down, but not too great to take away from the sheer awesome that this game was made of. A few things that might want to be stated though, the dialogue for the ticker tape machine for the red herring was a bit of a problem because my mind was thinking too far into logic to actually get it right the first few times. However, it was an excellent game and I hope you make a sequel some how.

Not too happy with the ending, but meh, really nice game no doubt. I would love to see a sequel, which can be even harder :)

P.S: first time seeing the last challenge, I was like "the hell man?!"

If anyone wants to report their playtime it would be a really intersting stat for me. The thing about a harder sequel is that as many people would prefer an easier one!


Rated 3.5 / 5 stars

Fun concept, and while I really enjoyed the logic puzzles I detested the pull down menus used. For some reason not all answers are visible when the menu is pulled down, and with no arrows to drag down to the other answers there is nothing to hint at there being more answers to choose from. After finally stumbling across the extra answers the puzzles came together easily enough, but this is a horrible programming misstep.

Please edit this game to include a side bar on the pulldown menus that can be used to see all the answers or expand the pulldown menus such that they show all answers at the same time.

Unfortunately I've looked at this and I just don't see a way to fix it. I'm using the Games Factory, and it seems to just draw dropdown settings from somewhere in the browser. This makes it very hard to fix.

If anyone is familiar with clickteam products and flash export and has any suggestions I'd really appreciate it.
