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 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!

Sucks because at the start it just freezes and nothing happens. Absolutely nothing...

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

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

I do not see why people like this game so much at all. It was not fun for me at all.

That was...interesting. In all honesty I'm not sure how I feel about it. The puzzles were difficult and a real work-through, impossible at first glance, and then they started to make sense...Thing is, though, it feels very incomplete. For something so story-driven with such deep thought as a core mechanic, it seems as though something very essential is missing. It's esoteric and fascinating, and I wanted answers, an explanation for just what's going on. I know it's a thought experiment, just a...I don't want to call it a /toy.../ What do I even call this? Jesus. I can't rate it fairly because I don't really know what it is-- I've never seen or experienced something so purely alien. I...I think it was brilliant? I think? The gameplay...worked. I do I even /rate/ this? It's no stars because I genuinely don't know what to put.

Now I will say this - the CONCEPT of the game is excellent and educational however its the logic of the creator that prevents the game from reaching its perfection. Meaning - whatever the CREATOR believes to be true is automatically true, therefore you cannot state another fact even if it is in fact a fact.

Meaning - there are multiple things in these situations that sound quite alike or sound logical to assume. However there is only one right answer and its not an opinion based thing - its a very piss poor design flaw where the creator makes it so only one thing is law / correct / right. I don't like the fact that I'm given 7 choices for one thing and only one thing works for it. I'm not going to sort through the combinations of multiple choices for multiple things to come out with something that makes absolutely no sense what so ever.

Maybe its a nit-picking problem, but I see it as a general over-sight in design. Either you give some level of choice, or you limit the options and make the options more varied / logical.

0/10 - Excellent concept - poor portrayal.
