Shadow Sphere Siege

Expand a shadow sphere in a monochrome void where size is the only law.

How to play

• Press Play and drift over the small food dots to gain mass.
• Roll onto any blob clearly smaller than you to absorb it.
• Keep away from blobs noticeably bigger — they can eat you.
• Use your bulk to corner smaller cells against the wall.

Why you'll love it

• Satisfying grow-by-eating mass physics with real momentum
• A risk-reward dance of hunting prey while dodging giants
• Smart AI cells that flee the big and chase the small
• Dynamic zoom that pulls back as your blob balloons
