I think the current method of updating works fairly well. Sure it might be a just a little irritating having to redownload download the entire game any time there's an update, but it's actually a fairly small download for most PC games these days. (If I remember correctly the last installer was just shy of 200MB.) At this point it might also be too late to implement a new method, seeing as every version of Telepath Tactics has been distributed through Adobe Air, and I'd be a little surprised if Craig had the time and funds to develop and implement a different installer. But don't forget: Telepath Tactics has also been lit on Steam Greenlight, and will likely be distributed through Steam at some point if you have a key.
