A challenging "open puzzle"

I've finished my game, now I'll polish and maybe improve graphics. The game is very challenging for what it looks like and I'm pretty proud on that!

The goal of the game is to achieve the biggest amount of score (yes as simple as that).

In order to gain points you will need to build things like Mines, Wind turbines, Factories, Markets and Banks.

To build something on a tile you need to meet all the building's requirement.

Building a house is a simple as having an adjacent farm.

But a bank will need a market, a worker (house), a mine (gold) and a wind turbine to be adjacent.

Banks will give 5 of score, house and farms -1, etc...

There's also terrain tiles that influence score.

Grass has no effect, water tiles can't be built on, forest tiles (the darker ones) multiply's the tile score by 2 and sand tiles multiply the tile's score by 0. So building something wealthy on certain tiles can be an advantage.
