We've talked about the brilliant Icarus Proudbottom's Teaches Typing but this is a new 5 part murder mystery, which you solve by typing quickly and accurately. Proudbottom's lies dead and by typing the funny and progressively surreal passages you slowly start to unravel the mystery. I have yet to finish all of the parts but am thoroughly enjoying what I've played of it so far. There are worse ways to while away time at work!
It's Proudbottom... but weekly! It's amazingly fun.
