Thank you very much! Then you should get two Steam keys when the time comes. :-)
There will be another 0.7.x release, but then I'm focusing on 0.8.0 and Steam, which means new levels and upgraded enemies. The game logic code needs major refactoring, and it has legal issues. Rewriting those parts takes care of both. I'll open up Steam Early Access as soon as 0.8.x is reasonably playable.
As to Kobo II (working title), I started running out of time and resources, and I realized I'd have to strip it down to something quite generic and uninteresting to be able to finish it at the time. So, I put it on hold, replaced the contract work with a job, and started working on a smaller project: Kobo Redux, which is also much more similar to XKobo/Kobo Deluxe in feel and gameplay.
However, I've kept working on Audiality 2 (sound engine, also used in Redux) and EEL (scripting language, used for some tools for Redux; may be used for GUI and high level logic in Redux 0.8.x), and I intend to update the Kobo II tech preview, and release it with full source code in the near future.
After finishing Kobo Redux, I'll look into reviving Kobo II - probably under a different name, as it's really a different subgenre, which doesn't appeal to all Kobo fans.
