3 stars: The game is indeed free to play. Ads are minimal. What I don't like are the hints. Usually 3 or 4 hints are needed if you get stuck. To give an example, the 1st hint was back, but that took me to a level there was nothing to do in. The 2nd hint offered was back again. The 3rd hint finally gave me something I could work with. There are no way to get free hints, as the free coins are greyed out.
3 stars: Great game so far. Think there's a bug. Can't pick up the crowbar out of the box in the shipwreck :-(
2 stars: This is only 2nd game from developers I've played. Took me awhile to figure out the concept on how it works. Giving 4 stars for graphics and music. But for me it all goes downhill. In order to solve many of the game parts you're jumping from one place to another, looking for clues. The worst is when 90% of the puzzles are unsolvable, unless you watch 10 ads in a row. Not relaxing or fun!!!!
