I believe you can do it. With so much experience, at least after so many projects, it's about time Matthew and effort. I am really impressed with the framework build, I did kind of notice that, but I was distracted by the game itself.
Just in case, because you mentioned about help, I started to make my own assets, a week ago, so far it's generic, but I am working on the game with a good friend, who knows Unity a lot, so, just in case that game works out, maybe you can check it out and if you like the "Voxel" art style, I might be able to help you and give you assets for free. Just because you are one of my favorite devs.
Good Luck Matthew! Keep on going and don't stop entertaining your fans!
Edit: The monsters in this game creeped the F out of me :D
