I have been slogging my way through the marathon badges for this game. I am playing the Main Entrance exhibit. Suddenly you need large amounts of coins to progress. I had to get 800 to buy a new front door which took forever given you get so few per game. By the time I earned them I had 117 of the blue icons, fish heads in this exhibit. I purchased my doors then thought great now I can move on quickly with all my icons. Nope. I got to do four badges at 5 a time and now I have to have 500 coins for new floors. Now I am sure it has nothing to do with the fact that you can purchase extra coins but just win the icons. I am so fed up with it I think I will just play random until I get these badges. Grrr!!
You have no idea how much I feel your pain, Raine.
I don't mind this game .. but I'm sure it's due to the fact I haven't played it nearly as much as you guys. I'm also playing puzzles that are still winnable without power-ups.
