StarLanes continues in development. I got Quests working, but they were buggy, and there wasn't a lot of uptake, so I didn't take them much further.
Things have been quiet for the last month as I've worked on SubWar. But I just submitted that for the contest it was aimed for yesterday. So I'll be back to doing stuff on StarLanes. Next up is to finish the build structure feature (you can improve star ports now) and the ability to buy currency. That will complete version 4. At that point I think it will be "full". It gets a bit hard to add things to an audio interface after a while and still have it do good recognition.
The development after that will be to blister out parallel games. StarTrade will probably be next. This will be a merchant focused game that will add in "space ports" in addition to "star ports". These are additional points of travel within a star system. Through trade between these points other features may be built at a point that will affect the game play of both games.

The unfortunate thing is that Amazon have been pressing hard for lots and lots of people to write skills. There are now over 1000 skills available. The problem is that the user interface they provide for discovering skills is very poor. As the number of skills has grown, the number of new users to StarLanes has plummeted. There is, currently, no way to advertise skills. The interface is set up so there is no link that I can pass around or put into ad copy. Can you imagine a banner ad with all the steps above in it? There are a few less steps for an echo users, but not many.
But I've been talking to Amazon about this. They are aware of the problem. However they have a company policy of never speaking about what their plans are. So I don't know if they are going to address this, or in what time frame. Ultimately the success of StarLanes is going to depend on if they can address this.

For my own part, the other project I mentioned, Sub War, is now in the public domain. Since it was a requirement of the contest, we decided to take advantage of that and create something that would hopefully be an inspiration, guide, and template for others seeking to create complex, interactive, multiplayer audio games for this platform. If you are a developer I would encourage you to check it out. There are 5000 words of documentation on design and development, 45 minutes of video, and 10,000 lines of annotated code. I am happy to answer questions about it if this is an area someone is interested in getting into.
