Interactive fiction game design for kids - repost 2

I want a few text adventure games to be designed for kids in the 10-15 age group. These could be in any genre - mystery, science fiction, etc. would want academic goals to be included. The interactive fiction game could be designed in inform game engine. It could be played on win frotz on windows or frotz on iPad. Math and science and general knowledge and language puzzles can be incorporated in the design. The game should be tested and several end points of the game should be planned. The game should be based on points. Could be on the lines of zork and bears night out kind of games.
