Hello everyone!
1 - Since the game map is basically an island, why don't we have the resource "FISH"? This is useful both for feeding workers and for extracting oil. We could have fishing docks to acquire fish, fishing boats with greater capacity, processing fish into meat, and fish scraps that can be transformed into animal feed.

2 - We could have trade options with other cities, allowing us to freely choose what to buy and sell without pre-defined contracts.

3 - Paving the ground could make vehicles travel faster, and similarly, vehicles could pass through the correct places on bridges and railway level crossings. There could also be a painting tool to define the direction of vehicle movement, allowing for the creation of streets and highways.

4 - Do railway bridges need to be so high to pass over certain types of obstacles, such as railway level crossings?
