Hakai-ou: King of Crusher

Sinopsis en inglés

You are a Japanese salary man, normal in every way... except that you've just been bitten by an evil space insect, turning you from a regular man into a rage-fueled monster. Destroy anything you can to fill your dopamine gauge, and reach the end of the stage to continue your transformation from a normal human into an enormous kaijuu monster, all the while avoiding the police and the military trying to stop you.
