For me has been easy to catch the concept, the "Monster tamer" genre was like... a bit taken out of the hat, but man, great art, it's simple and looks good, not a single complain about it, and the difficult is very hard the first time, but once you realize how the game works its super satisfying to go for the pieces and try to put them somewhere, when the game evolves you begin to look for certain pieces instead of going like... randomly taking every piece, at least, that's how my journey was (XD),
you have to put some sound into this, is very addictive!
