Need help finding old mobile RTS.

I need help finding an old rts game on mobile. I don't remember the title but I do remember some details. The game used super simple graphics. 1 or 2 bit dont remember exactly and can find similar in both catagories. Resources were mainly gained through mining or farming "gold, mana, and stone were mined while food and wood were grown", you could move armies grid by grid or press and hold to lay down paths marked by arrows. Troops where built at castles for standard troops, wizard towers for monster troops, and shipyards for sea troops. You could build catapults to fight enemie armies or ships from a distance. You could also build sea mines or walls to prevent enemie ships from passing certain routes. There was one primary map and more maps you could buy for a few dollars. I would greatly appreciate any clues.
