The Stone Cage

This is the other 2009 24 Hours of Inform entry. What surprised me is how comprehensive the game is, it really does have a non-default response for most things you try. Even uncommon ideas like eating, drinking, or smelling certain objects will give you specialized responses. Descriptions are particularly short and succinct, and it never feels like you're missing information you need. I thought the caveman theme of the game was a nice change of pace as well. It's impressive for a game that was made in a short span of time, and I definitely prefer it to Semi Intelligent Design.
