Blue Toad Murder Files

We started off saying, "We do Buzz, and Buzz has done really well. But what is Buzz? It's a bit like Trivial Pursuit." And we thought, "Well, what else is there that's a bit like Trivial Pursuit?" And we got onto Cluedo and the whole murder mystery idea. Can we do a social murder-mystery game for a similar crowd to Buzz?

That was the first thought, and we had a few different attempts at it. The first idea was a boardgame, to make the gaming equivalent of Cluedo. But then you start thinking there has to be murders and you get onto Miss Marple, Poirot, and everybody knows Agatha Christie stuff so we thought about making [TV and boardgame] meet. Obviously this is a computer game not a boardgame, so that's important, but also we wanted bits of a TV show. We needed some action.

The bit inspired by TV was the off-screen interaction between you and your friends in your front room. You playing around and asking "Whodunit?" before it came up. That seemed quite exciting: the fun bit.

But the problem with a lot of those Agatha Christie things is that it's too hard and no one ever gets it. And if they do get it then it was for the wrong reason. What we've done is make it a little bit easier. We want most people to have a good go at getting it.

You can play with between one and four players. You choose your detective, all stereotypes: the Miss Marple old lady, the big pompous detective, the Enid Blyton schookid, etc. They're the Blue Toad Agency: this fictional band of detectives who solve murders. They all end up stuck in this little village, and needless to say that within the first five minutes there's a horrible murder and they go investigating who they think did it. The whole game is a deductive puzzle; you get all the information and you make your case. But in between those there are micro-puzzles: put these facts in order, for example. It's a bit like Professor Layton. But unlike Professor Layton these are tied more closely to the story.

Originally we wanted you to go round asking questions, specific questions, from dialogue trees and what-have-you. However, we decided you actually need all the information. Often when you play a game like Monkey Island you select every option anyway - you don't select three and decide that that's enough. So what we ended up doing is creating quite a linear story. Basically, everybody will see everything. And we know what you'll see; we know you've got all the facts you need to make your mind up, and we've organised the story in a way where you won't have all those facts until the end.

About an hour. Again, that was another of our criteria. Ideally it's going to be played multiplayer, and we want people to be able to say, "I've just downloaded this murder-mystery game, it will take an hour, do you want to play it with me?" It's the same length of time it takes to watch an episode of Poirot or something, rather than a three-hour game where people maybe start to drop out.

They're pretty railed, to be honest. Occasionally you get options - you can go to the pub or you can go to the train station - but you'll have to go to both of them at some point anyway. [Then] it's basically a cut-scene; you go to the train station, you see the Station Master chatting to an old woman, you join in the conversation. The Station Master wants you to help find the lady's lost bag, and you'll get the interactive gameplay puzzle to find her bag. At the end of that he'll take you to one side and you'll ask him about the murder. And that's basically how the whole game works: little bit of information, puzzle, another little bit of information, etc. Once you've done all of those, you'll be asked, "OK, so who was the murderer?"
