I like the game, good graphics and story. You need A LOT of coins to pay for forensic stuff. You also need coins to upgrade 4 offices. Upgrading offices is suppose to refill your energy bar faster. The hidden pictures are timed, (1:28mins) and hints are costly. There is a daily challenge, and I mean a CHALLENGE! The one I tried gave me 6 mins to complete 5 different puzzles.(which I could not do) you can keep trying for 1 energy per try.
One of the daily puzzles was to find 8 differences between the 2 pics...problem was, the pics are bigger than you realize and have to be expanded.
Coins are hard to come by as you only get like 30-50 per search and it casts 20 energy per search. I did have the opportunity to double my coins with an ad after each search...annoying.
I know you want to make money, but when the game is so stingy, you chase us away. Nobody wants to spend money and get nothing in return.
