there is going to be a shop but it's going to work differently, you purchase items you talk to the shopkeeper and a purchase menu will come up, also you can sell items(coding is done,100%) anything you can help on, not sure but if I think of something I'll be sure to pm you.
EDIT:@ Xiphirx
hmm, maybe you don't get a full 60 fps?
in the next demo, I'll optimize it a bit and put an fps tool on it.
