Graveturn

The game

Graveturn is a one-button runner through a neon sunset corridor. Tap to flip gravity between the floor and the ceiling: gaps swallow the unwary, spikes shred them, and closing doors crush whoever is on the wrong wall when they slam. The corridor accelerates the further you go, and every metre of distance is the score. Visually it is all neon silhouettes on a single-colour sunset gradient that slowly cycles hue, sharp geometric obstacles, and a player ship wrapped in bloom glow.

How to play

• Press Space or click/tap anywhere to flip gravity toward the opposite surface.
• Run on the floor or hang from the ceiling — flip early enough to clear gaps and spikes on your surface.
• Closing doors force you onto their side of the corridor: be riding that surface when they arrive, or be crushed.
• Speed ramps up with distance; the run ends when you fall through a gap, lose grip of the ceiling, hit a spike, or get pinched by a door.
• Score is your distance in metres, counted continuously and saved as your best. P pauses, M toggles sound.
