As I continued to work on 0.11.x update I realized that I'm building on an unstable core. As I eluded to in my previous update, the biggest challenge has been shedding what's already there. I also previously rebuilt Serenade of the Sirens (SOTS) but I just recreated the same game with "better code". This time I'm rebuilding with the intention to change things radically for the better.
As of now things are good so far. I'm planning to have a playable build for the new version of SOTS by the end of the year and I'll give more details in a future update. Also one thing to note is that the demo and full release versions may be identical with the initial release of 0.11.x.
