Good night!post before going to bed
Good question! It takes roughly 3 seconds to collect everything. 2, if on a faster PC.On pc, pay 5 diamonds so all your collection can be done for you?
Edit: Collections on app is super easy, just swipe your finger over the buildings
My finger swipe is so much more efficient and empowering!Same on PC: swipe your mouse over everything, and you're done.
