@Atchet – I always reply the email PayPal gives me. You can send another from a different email if you didn’t get it.
I’ll address some of your questions, as most of your suggestions are part of “not finished stuff” or will be coming in the future:
- You can open Backpacks and Small Bags to place items in to reduce decay and weight.
- When decay reaches 0, it decays – just like durability.
- You can fill caves with dirt/sand/gravel, etc.
- You can technically mine with any tool. The bonuses come from it’s attack value and it’s durability might be a good factor in deciding which tool to use.
