Well now, that is amazing! The screenshot looks awesome! I'm very impressed to hear this is just js too. It's a powerful little bugger, that's for sure.
All my experience with js comes from making html cyoa games (expansion mansion we completed and opposing force was put on hold).
Of course, all we had was the .2 release, so it's fantastic to hear the many changes and improvements you had in mind to move forward.
If you get the time (and relevant motivation at the time) I would love to see more of this awesome project and wholeheartedly wish you all the luck in the world, as well as any help I can offer.
