The game state in the PHP version can be saved by saving the bookmark. The URL contains the game state (it actually contains all the choices made, and the game state is regenerated from that.) So the PHP version is REST-ful not that is anything to cause players worry. The Flex version will save its state automatically on the client.

The game is scripted in Henge, a home-brew language for CYOA style games. The process of producing software interests me as much as the finished result. Henge is deliberately restrictive and limited, partly to simplify its programming, partly as I wanted to produce simpler games.
