A quick note: Craig Smith has ported Frotz to the iPhone. This means that you can play I am not kidding hundreds of text adventures, including all of mine. Frotz is a free download in the iPhone App Store. (It's a Google code project.)
The app comes with a nice stack of games. (Including the famous Zarf games A Change in the Weather, Spider and Web, and The Dreamhold. Also the famous not-by-Zarf-but-he-shows-up game Being Andrew Plotkin.) But the really boss trick is that it lets you browse IFDB, directly from the Frotz app. Select any Z-code game, and it's automatically downloaded and added to your game list. Think of it as a mini App Store for IF -- only all free.
(I really have to adopt some cover art for my games. I did a cover for Shade that I rather like. For the rest, I will go back and look at Emily Short's IF Cover Art Drive. There were some great contributions in there, but I never bestirred my butt to accept any of them.)
iPhone Frotz is a 1.0 release, and I see some rough edges, but very small ones. The worst problem I've found is that The Dreamhold plays very slowly -- not every move, but when you do something interesting. This bothers me, because The Dreamhold is my shot at an introductory IF game -- it's designed to coach players who have never tried IF. I want it to run well. My current theory is that displaying italicized text is much slower than printing plain text.
More later. (I forgot to charge Mr Shiny since getting back from vacation, and I should save what's left of the battery for, maybe, receiving phone calls.)
