found it a bit slow at the beginning. Unlocked area 2 but found out area 1 was paying more in therms of wood. but after 10 times doing the same level and 4-5 upgrades later nothing is added to the game. Am I doing something wrong?
yeah, the 2 levels that literally show a forest on the map are the best place to grind wood hard.
similarly there are 2 stone levels in the dessert that can be farmed for stone. even though the dessert sucks since indestructable pillars and stuff appear there making some levels near impossible
