there is no point playing as the increase of your power is in multiple dimensions and the scaling in difficulty is lineair, so no challenge what so ever, you cant lose and there is no end.
BORING!
How to stop the the game, well kill all the enemies using abilities while your last soldier dies then move on to the next chest and wait for hours till your last dead soldier opens the chest with a mighty kick. 2 days and still waiting :)
