Ok but not worth a dollar

I was so excited to get this app because I love the show tanked! However, you cant do much. Theres only two games and no quests. You also have to wait like 12 hours until you can clean your tank. Lastly, it doesnt explain what the shells are. So far, I have none I think you have to pay extra money just to get money to spend in the game, so you cant even get everything!!! Its not worth a dollar until they get an upgrade.
