Health bonus

A health bonus (or health potion) is a powerup that appears as a small blue bottle. Picking one up increases the player's health by 1% (2% in many ports, including the Sega Genesis and Playstation 1 ports) up to a maximum of 200%. (This limit can be altered in DeHackEd.)

Health bonuses are included in the items percentage displayed at the end of each level.
