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!

Add a scroll bar on the drop downs. I couldn't figure out what was going on there for awhile. Once I discovered there were other options that I couldn't see things became much easier logically. However, when I pressed the down arrow it would change all the answers in the column - causing me to have to resolve multiple logic problems over again. Usually I would forget that I had to re-correct them to begin with and would get the answer wrong multiple times before I realized the error.

Aside from that, it was a decent logic game. Different than any that I've ever played so it was enjoyable. But the controls had me on the verge of quitting many times. For that reason I couldn't go any higher than a 3/5.


Rated 3 / 5 stars

Good idea, but leaps of logic are horrifying. How does protagonist even knows a) he's actually alive b) he's actually human? It kinda defeats the point of making game about person in state of philosophical uncertainty - protagonist's stance is heavily ignorant, too much relying on what is familiar, and complete inverse of philosophical one.
Also, there seem to be problems with controls, especially with the buttons and dropdowns. Honestly - people (amateurs) out there are making games with split second ten-button-at-once-pressed commands, and you fail at making a goddamn dropdown, interface standard that's been used in software since 90's? And we're in 2010's? That's a fail.
Also, I'm disappointed at the story. Or more like, lack of it.

Agreed. The sequel will be better!

I liked the game, but the two bugs on two levels I encountered ruined the game for me. On level 7, there was no correct answer for the second line second dropdown. Same thing happened on the last question, last option. If these were fixed and the game was a bit longer, I'd vote 5/5.

level ten made no sense, i dont care how smart you think you are, or how many levels you "did with out any hints" I honestly needed a lil more like what the arrows represented or something, i mean really fun and mind stimulating game but i think theres something off with lvl 9 and ten was just off, i just guess with similar symbols till i got it, it was like A -E O or something? like there was no clues to that
