The game is fun to play, but I've noticed that after several updates the developers are trying to increase play time just so you'll end up spending real money on the game. Especially with the find the treasure mini game where it's forcing you to go through all the waves and the treasure chest isn't really in a "random" spot, but always forcing you to go through all 5 waves. Also, the fact they reset the whole story mode even after you've beaten it.
