We created pseudo-random numbers with the help of hardware timers of MSP430Puppy microcontroller and time of last button press. By utilizing internals of the controller to the max, to reduce redundancy, we built LED follower with minimal and necessary circuitry. Here the player needs to press the buttons corresponding to the on LEDs within the given time frame where the speed increases exponentially with the level. We built the same on a copper board with same circuit design.
