How AI is used
Starwhisker is a solo indie project. During early development, some placeholder assets and development materials were created with the assistance of AI tools to help prototype ideas quickly and focus resources on gameplay development. As development continues, these assets are being progressively refined, replaced, or supplemented with original work created specifically for the game. The goal is to ensure Starwhisker develops its own distinct artistic identity while remaining transparent about the tools used during its creation.

About Starwhisker
Starwhisker: Spectrum Survivors
The universe is fading.
The ancient Starwhiskers once protected the light that connected every corner of the cosmos. But after a cat-astrophic event shattered the spectrum, darkness began to spread. Now the Void hungers to consume what remains.
Play as Luma, the last light of the Starwhiskers, and fight your way through endless waves of alien invaders, corrupted creatures and ancient horrors. Harness the power of light, collect powerful upgrades, and master the colour spectrum to survive.

Shift between different wavelengths of light to exploit enemy weaknesses and maximize your damage. Every color has its place, and mastering the colour spectrum is the key to survival.
