About

Marunomi

Features
Read full description

A surreal idle creature-raising game where a deadpan fish gulps down prey and evolves into weird, creepy-cute forms. HOW TO PLAY - Tap a prey fish, your fish dashes and swallows it whole - The more it eats, the more it evolves into bizarre new shapes - Evolutions are random - you'll keep playing to see the next weird form FEATURES - A "Dex" of 15+ evolution forms to collect - Hidden evolutions (night-only, gold-drenched, and more) - A deadpan hero who mutters quirky one-liners - 12 endings - it gets oddly touching at the end - Idle-friendly: prey gathers while you're away. Great one-handed game * Don't worry - the fish that get eaten are actually alive and well, living happily in another tank. Cute, yet a little unsettling. You'll laugh, then feel something. Raise a weird little fish in your spare moments.
