Wait for the price to go down.

Gameplay is so quick its more of a mini-game - DEFINITELY not worth $3 compared to everything else out there. Its over so quick theres no time to enjoy playing. Hold out for a zen mode or something where theres no opponent and therefore no time constraint. Hope that day comes; til then the devs are laughing all the way to the bank. 99¢ tops (but if youre patient it will be free eventually).

Coolout about bit bit blocks, v1.0.1
