Rockman Diver

Rockman Diver is a game released for mobile phones in Japan in January 2011. The player controls either Mega Man or Splash Woman and keeps falling continuously on a underwater pit of spikes, needing to avoid them as much as possible to stay alive. The player can also destroy spikes for a limited amount of times. After some time, a boss character like Bubble Man and Dive Man will appear, and touching him will make the music and scenario change to resemble his stage.
