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 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.


Rated 5 / 5 stars

first impression: concept: awesome.

second impression (at 6/10): very clever. so far you haven't gone beyond implications, biconditionals (iff) and conjunctions/disjunctions. going much beyond that would be pretty far beyond the capability of your average gamer and i assume you want people to at least try to finish this and in a reasonable % of cases, succeed, so that was wise on your part.

third impression (at 9/10): still fun. i wasn't sure what a red herring was, but i still completed the puzzle. i think maybe you should have defined what a red herring was. it was obvious to me from the context, but it may not be to some others and that may stop them from completing the game.

fourth impression (at 10/10): i've never seen the underscores under the and/or symbols before. it wasn't necessary. was it just to make things look more complicated than they really were? 10/10 was one of the easiest puzzles in the game.

final impression: wasn't too pleased with the ending.

was still fun and a definite 5/5

tjubert responds:

Yeah, a lot of people don't like the ending. I like some of the thematic stuff - the mechnical puzzle at the end, the integration (or lack thereof) between emotion and reason, and the character's ambivalence to death. But it could have been better, I'm sure.


Rated 5 / 5 stars

Spent an hour on 9/10. Didn't ask my brain anything. Wanted to test my smarts. Couldn't finish 9/10. But DAMN! Is this game hard or what?! Good show. 10/10 Very unique.

Wow. I give this game all of the stars because it's brilliantly made and deserves much more attention. I was sitting there with a pen and notebook working out the problems in math formula forms, debating to myself aloud how some of this was confusing and how the ending selection should be and it kept me thinking throughout the entire thing.

I was even more surprised when I got the final challenge on the first try when I really had no idea what I was doing at all. Ha. The challenge of contradicting The Machine was the hardest, but it was mostly because I had things out of order. Well done. Loved it! xx

Thank you!

On the whole decent, but nothing special

But... why is it 18 megs?

tjubert responds:

Because I didn't know anything about flash when I started and didn't use transparency in images to save space. Sorry!
