I love the art work, it's the kind of art that remains untouch with time because it's not serious!
The idea is funny! I'm waiting for it but 2018!
Keep the sense of humor and try to implement a nasty but very funny anti-pirates functions:
- Like orc mafia coming every day to take your money
- Your employees steal your food until you can no longer serves the customers
I'm sure you will come with something funny
Also, please keep up the communications (YES it's time consuming...!) because building a community will help you at the end when you will need to talk about your game!
Good luck for the next 2 years of development!
