About game
Cytosphere: Cell Defense is a fast arcade defense game about protecting a living cell. Rotate its membrane with one gesture and guide incoming particles into four colour-coded sectors. Nutrients and energy strengthen the cell, while viruses, parasites, and toxins demand precise reactions. Build a combo, trigger a pulse, choose mutations after waves, and fight bosses. Every seeded run offers a fresh attempt and progress between runs.
How to play
Rotate the membrane with a mouse, touch, or keyboard. Match green with nutrients, cyan with energy, violet with viruses and parasites, and orange with toxins. A wrong match damages health and raises infection. Maintain a combo, charge the pulse, and choose mutations between waves. On desktop, press Space for the pulse and Escape to pause.
