really unfortunate that the kickstarter didn't succeed, the game showed a lot of work and promise! :D I still like it for what it is. In my opinion, sure it had a lot of mechanics and features similar to Zelda, but there are so many professional games out there that take from others as well, in my perspective, I don't see that as a valid reason to shift away from it, but you are the games developer after all :D
I wish you best of luck in your latest project, go with it and you'll succeed this time no doubt!
