You have two gauges: red and blue. You have two coin sources: a ring and a switch. Move your cursor through red rings to summon 8 red coins - The ring reappears when you collect all red coins. Tap the blue switch to summon 5 blue coins - These coins disappear after a few seconds, and the switch moves on its own. Collect coins by moving your cursor near them. Coins fill up their respective gauge, which also gradually drops. A gauge is empty? Game over! The number at the bottom left is your total coin count. Don't explode
