Review with minimal spoilers.

This game has 3 phases. First is slow, 2nd makes 1st faster and 3rd is endgame. Game gets very intresting in 2nd phase so I suggest you stick up until then. Its fun for couple hours and there are multiple ways to play the game. You can go back to 1st to make 2nd stronger or reset 2nd to make 1st stronger.

Much, much better than other minigames with lineral gameplay.
