Fifteen Monsters All In A Row is a short text adventure/twine game (which should work in any browser), where you have to confront fifteen monsters (in a row), which I made for/with my five year old niece and two year old nephew, who designed the monsters, and wrote some of the stories. The game contains 15 monsters (all in a row), several secret monsters (occasionally in a row), multiple solutions to every problem (almost), some exciting stories (occasionally), at least two jokes, and even a super secret special ending.

Playfic is a community for writing, sharing, and playing interactive fiction games (aka "text adventures") entirely from your browser, using a bizarre and wonderful "natural language"-inspired language called Inform 7. I wrote a bit more about it on my blog, along with some screenshots.
