Aoi Blink (青いブリンク) is a platformer based on the 1989 TV anime series of the same name. In each stage, you're assigned three characters who you can switch between by hitting the select button. The front character will determine the party's jump height and attack, which is different for each character. In order to beat a world, a red key needs to be found in one of the stages. Due to the multiple paths that are allowed, this means that one can skip many of the games stages if they already know where this key is hidden.
Normally, when one loses a life, Blink, a blue pony, flies down and brings the characters back at half their maximum health. However, if you pause, you can select to expend one life to completely fill your life meter.
