To say that the game is poorly balanced is an understatement.  It's designed around mobile "strategy" game PvP a la Clash of Clans, where you send out a ship or theoretically a set of ships against an enemy set of ships.

No orders can be given once the level starts, and you don't seem to get much between runs until about run 25 or so.  This might be functional for the developer as a scam game with plenty of microtransactions, but for players, you can expect absolutely nothing out of this game.
