Honestly, I downloaded this as a random thing to waste time. I've been playing for 2 days now. Finished Sacred Stones, and it was a fantastic game. Some of the puzzles made me want to slap the creator (in a good way), cause they were brutal (talking about you, damn bird puzzle). The artwork is great, the stories are more then decent, and most importantly, the puzzles are fantastic. I'm working on Trapmaster now. I also want to mention that the price for the keys is quite decent and not overly expensive like many games like this. You also have the option to get a few free keys every day by watching some ads. Worth it. Looking forward to more. Can't really think of any negatives. Some puzzles did seem a bit unfair at first (fight against ice god), but hey, it makes victory sweeter.
