Frustrating but rewarding and quite adictive.
It's nature, music and animation is quite relaxing on the other hand, that's a big contrast of the frustrating trial and trial and error and error and error. The marbles become hard to target since you'll need to calculate the distance and angle in order to proceed. This game will challenge your patience like no other, it's a great exercise of how a frog can push your colored buttons.
This game came with the Bejeweled 3 game, and it's an excellent game package for all the puzzle goodness that you can get for a quite low pricetag. This game is not for everybody and it will suck your time away, so be aware of the temple of Zuma.
