Vampire Castle is a Halloween night on your wrist: Dracula's castle silhouette on the horizon, a large crimson moon, and bats swirling through a dark red-purple sky — all behind a big outlined time display. The whole scene is drawn with polygons, not a bitmap. It uses almost no memory, adapts to any screen resolution, and stays in motion while the watch is awake: stars twinkle, castle windows flicker, and bats drift across the night. Time stays large and readable, with a dark halo so the numbers remain legible over the scene. Below the clock you get the date and a stats row for heart rate, steps, and battery charge. It looks rich on AMOLED displays and quantizes correctly on 64-color MIP displays. On AMOLED devices, always-on mode is burn-in safe: a low-power screen with dim time and date and a small castle glyph, jittered every minute. Fully offline. No settings needed. No permissions beyond standard sensors. The face shows numbers only, so it works in any language. Supported devices: fenix 7 / 7 Pro, epix 2, venu 2 / 2 plus / 3 / 3s, Forerunner 955 / 965.

First release of Vampire Castle: a procedurally drawn Halloween watch face. Dracula's castle under a crimson moon, with twinkling stars, flickering windows, and drifting bats behind a large, readable time, plus date, heart rate, steps, and battery.
