here's some tips and tricks, and info, for those that couldn't figure it out!
-you can place roads on the water tiles, BUT the water road tiles can't connect to other water road tiles, you'll see that these tiles can be placed in an alternating pattern, it's best to use the water road tiles to connect to other paths or to pens, or to fill up the water trough
-while crops can be placed on the sides of the ground tiles, the crops can only be hydrated by a horizontal water tile, not the vertical 'running water' tiles.
-when placing troughs and markets, the farmers will prioritize the market over the food troughs, so place the markets away from the pens in order to decrease the chance of the throughs being empty.
-the farmers just walk anywhere, they don't immediately go to the market when they have a crop or pig, so be mindful to have many markets scattered everywhere
-the water tiles cannot flow upwards or left/right, bit of a 'duh' but it's worth knowing!
and most importantly!
you need 750 for the second level, and 1000 for the last level
