100パーセントラブペット

Life in an aquarium

100パーセントラブペット is a PC game about a pet kept inside an aquarium by a lonely “Mysterious Creature.” You swim through the tank, fight enemies, and use the enemies and items found there to raise the creature’s affection for you.

Fighting and oxygen

Defeating enemies increases your Love Level, while your HP and oxygen must last. Oxygen decreases as you swim, so you need to reach the surface and keep your head above water to breathe.
