Meridian: Age of Invention - Level 1 ~ 6

In this game, houses don't produce gold automatically. Instead, deliver food or letters to earn money. Delivering a food package gives 100 gold. Delivering a letter gives 150 gold. Oh, open chests in the map for more gold! Collect ores in mines to build and repair stuff. A bag of ores from mine worths 300 ores. A single worker can mine ores, but adding one more worker makes mining process faster. You may buy or sell ores in the market. In some levels, you 'must' buy something in the market, as Level 5. Workshop provides bicycles for couriers. Couriers will move faster with bicycles.
