Gothicorn

A mobile-first js13kGames 2026 entry for the Unicorns and Rainbows theme.

You play a black goth unicorn who has had enough of rainbow-farting cousins leaving magical mess everywhere. Enemy attacks increase Beauty, and reaching full Beauty is defeat. Tap to fire ranged Gloom bolts, hold at close range to absorb spectrum and build VOID, then use BLACKOUT when VOID is full. Between encounters, clean up the rainbow mess to become properly drab again.
