Gave it a go before posting it and it's a cool army management wave based game. Free to try, full game unlock priced at $4.99 (?). Have your army fight automatically and cast cooldown based spells to help your units or summon more units; get some gold and a few upgrade choices, like more/new units/spells; spend your earned gold on upgrades for said units and spells; survive as many waves as you can until you die (I managed to reach "Endgame 4"); repeat. Simple and engaging gameplay. I liked it.
