Great sequel to a really fun game. The graphics are even more impressive and new game mechanics such as the mining cart add to the enjoyment. The game runs smoothly on my iPhone 5. For the people complaining about lag or crashing, this is a new game, so it's going to be optimized for new devices. Giving bad scores because your device can't handle the game is unfair.

Great level design, challenging gameplay. A lot of replay value.

Great game

I've only played about 30 minutes, but I'm having fun so far.
