Easy game, a bit sloppily made, but not bad overall.
You can't use the 2x speed until you have unlocked faster workers at the company office.
Best things to sell are:
Hill: Chicken, Meat, Fish.
School: Hotdog, Sandwich, Pudding.
Market: Chicken, Meat, Fish.
Beach: Caviar, Lobster (luxury foods)
Ship: Luxury foods; Caviar, Lobster, Steak and Ratatoulie.
Coffee sells at most places, Chocolate drink is better at school though.
Always mark up the prices, I was comfortably able to sell Chicken for 85, which is 850% mark-up on wholesale.
I rarely used any vehicle above the pedicab? The one that costs 4,500, simply because the cost of the worker goes up with higher stands. I would only recommend using higher vehicles on Beach and Ship, when you can sell luxury goods to cover the cost.
The game has potential, the art style is nice, the general game play is decent. But if you get too greedy and force people to worry about energy, micro-transactions, etc. Then it may suffer.
