Enemies will sometimes drop [[#Items Dropped by Enemies|power-ups]], coins and extra lives upon being killed. One power-up at a time can be stored in a slot in the top-left, and can be activated by pressing {{Key|Space}}. If a power-up is picked up while another is already being held, the new power-up is consumed immediately. Power-ups last only for a short time. | Enemies will sometimes drop [[#Items Dropped by Enemies|power-ups]], coins and extra lives upon being killed.
