Moon: Remix RPG Adventure (1997)

In this "anti-RPG" adventure game notable for parodying and subverting common JRPG conventions, you level up by loving, not fighting. Revive dead animals and bond with everyone around you to obtain the most important thing in the universe — love.

Storyline

One night, a young boy suddenly gets sucked inside the world of a role-playing video game. As it turns out, the "hero" he has been controlling this whole time is actually a murderous villain obsessed with collecting experience points. The boy has to undo the damage and stop the "hero" before it's too late.
