Star Castle

Breach the rings. Survive the zap. Break the core.

Star Castle is a fast, procedural space shooter inspired by the arcade classic. Carve openings through three rotating shields, evade the central cannon and hunting sparks, and land eight hits to destroy the core.

Ring collisions bounce you away and zap you for two seconds: no thrust and half-speed shots. Momentum-driven flight, screen wrapping, and increasingly dangerous rounds keep the pressure on.
