🧠 Core Gameplay (Typical Fan Version)

• You play as an alien — often Sylvester (the green UFO-like alien) — and your goal is to eat / kill all the fish in the tank before time runs out or before the tank’s owner defeats you.
• Fish fight back — Guppies run, breeders spawn more fish, carnivores actively chase you.
• Power-ups for aliens — You can gain shields, speed boosts, or special attacks.
• Multiple tanks / levels — Each with different fish layouts and defenses.
• Boss fish — Giant or special fish act as final obstacles.
