Niche Game: Space Station Silicon Valley
Each type of animal has its own set of abilities which must be used to solve environmental puzzles in the game. The sheep is one of the first animals you encounter. It has no attack, but it can glide slowly down, floating like the little puffy cloud that it resembles, which lets it cross long gaps easily. Also in the early stages you can become a dog which can jump and bite. Hyenas have contagious laughter which causes area-of-effect damaging hysteria. Pigeons can grip dormant robots and carry them from place to place. You get the point.
I recommend Inferno as a great template on how to build on a familiar theme (hell) and insert characters that are larger than a wonderful plot. One of the recommendations that many ‘How to’ books stress is to make your character change from the experience in your story. Allen Carpentier changes like few others that I have read before.
The thing I love most about Cold Words is that it takes what seems like a pretty simple spaceport deal and turns it into something really exciting by putting it in the point of view of a 6’4” drug-addicted wolflike alien with ulterior motives. Boy, did that add stakes and complications!
