Great idea, terrible execution. Need to watch ads to make any form of meaning progress but the ads constanly freeze. You have to close and reload the game. The ads when they freeze take time of the 2x multipler but not the construction times, so you can see it is stacked against you. The ad removal is $15 lol and they still want you to pay for even more throughout the game. Thought is was a cool foncept but it is a cash grab instead.
