Aquarium Simulator: Game Design Doc

A Simulator game set in an Aquarium world focused on Base Defense, but the camera is top-down.

Core loop

Do the core action to earn currency, spend it on gear and pets that make you faster at base defense, unlock the next zone, then rebirth for multipliers.

Monetization plan (suggested prices)
