About Bitlab
What could be simpler than throwing colored balls in tube? Don't think so.
You'd better prepare your finger before playing Bitlab. Also, make sure that your device is securely fastened in your hand or on the surface. After tapping "Play" button do not relax. Seriously. Just try to overcome 15 stage and collect bit-points as much as you can. Difficult? Aha! Have fun.
