Just beat it! Some tips
-You can remove trees by placing a lumberyard in the same place twice
-There's no penalty for using the 'remove' card to remove buildings
-Try to place trees strategically so there's 4 surrounding one block so you can harvest them all in one go
-If you place fields strategically you can harvest 4 completed fields (x4 fields) with one mill
-Mills can stack
-Use the 'remove' card to take out a house in the centre of some houses to place a bakery for more coins.
-Quarries can be placed one top of stones, removing them.
-If you place islands around a body of water it will create a lake. You can place a pier in a 2x1 lake, which prevents the pier spawning all the scenery around it. Lakes are otherwise pretty useless
