Ok, PL&DB is an unusual game due to lack of action, it focuses on puzzles and wit to entertain people. DO NOT BUY THIS IF YOU DO NOT ENJOY PUZZLE GAMES! Most of the puzzles CAN be solved by guessing, but if it's a harder puzzle, you might need to look closely at the question. Some are actually trick questions, while others require careful calculaations. Some puzzles Have to be beaten in order to progress; if you have trouble with those, you can use hint coins to help you, however, they don't give you the answer. About 2 hint coins can be found on each area, and can be found easily by randomly tapping the stylus around. I would not reccomend using hints unless you are absolutely stuck, or on a required puzzle. There is no multiplayer, however you can download a puzzle every week on wi-fi, which helps add replay value. Also note that failing to solve puzzles will hurt your score (in picarats-used to unlock bonus features) and can be prevented by frequently saving. Also, keep in mind that some puzzles have to be found, just like hint coins. Overall: 7/10 (if you've got a good head on your shoulders)
Music: 6.5/10 (nothing special here)
Playability:7/10 (fun til u get stuck)
Multiplayer: 2/10 (try solving out the puzzles with friends, adds some interesting insight to the game.)
Graphics:9/10 (nicely drawn, wont feel repetitive at all)
Hope you enjoyed this. ~Aerostar
