You may have noticed arrows have recently been added to the game. This came about as many players let me know they didn’t know where they should build their towers at the beginning of the game. Hopefully this should make it a little clearer.
The green arrows show where your minions will travel and vice versa for red, so you always want to build your towers beside the red arrows. If anyone has ideas on making them look better or signifying minions paths and where to build towers in a different way let me know.
Also if you’re colour blind let me know how they look for you, can you see them in the screen shot and tell what colour is what with ease? If not I may change them to red and blue.
