I usually only lurk, but…Hey, . I purchased your kit, and would like to say thanks for putting in all the time to construct it. I look forward to getting some time to build it and see what I can make out of its features! 
I would recommend if you are wondering where you should direct some attention (which I doubt!) I’d say take a look at dungeon level instancing, and a basic party system. Those are two things I have been scratching my head about as I try to plan features. The dungeon level instancing more than anything!
Once again, thanks for the efforts!
