G.G Series: Super Hero Ogre

An evil army is on the march! Confront them and save the day in this
superhero fighting action game. Each time you defeat an enemy with a
Hero Attack, your Hero Gauge goes up. Then, with simple button commands,
you can use the charged-up Hero Gauge to unleash powerful Superhero
Attacks on your foes. Continue to land Hero Attacks to keep the Hero
Gauge charged and perform a devastating chain of Superhero Attacks.
After you destroy the lesser enemies, a boss will appear. Defeat it to
clear the level.
