Hi
Thank you so much for posting this

It looks really great, i looked at the video too

.
I really wish i could help, it looks like such a good project and that you have already made a lot of progress. Which is a major plus.
Sadly it also looks like you would need a lot of assets, more than i could help with since I am already helping out with another project (not Zelda, but Zelda influenced) which is eating up a lot of my time and creativity and i wouldn't want to short change you (even assuming you liked my art).
In addition you need good pixel artists and if its not traditional media (especially pencils or ink) i'm kind of all at sea anyway.
Spelling and grammar and general prose i could probably help with... if that would be useful, and i'd be willing to playtest... on the understanding that i'm not hugely experienced with turn based RPGs.
When i comes to maps... Campaign Cartographer is actually pretty good, if i am understanding what you mean (ie. for creating graphics, not placing playable items), it might be worth a look?
Truly, all the best with this, it looks fantastic. I'll sign up to dropbox and download it.
Edited to add:
Oh, Oh SpritingBrad's pixel art looks awesome. I don't know if he's working on something else, but maybe you two could talk?
Am i interfering too much... its ok to tell me to stop if needs be.
