A game of rhythm, reaction, and concentration.
You must keep the numbers in the grid above zero. The numbers will decrease in value over time. To add value to the numbers click one of the three execution buttons at the bottom of the screen; then select a number in the grid. The usage of execution buttons is limited by the digit meter to the right, so add wisely.
