Sequence Stage

A ship flies in on a sequence authored in the Timeline, with sound cues, then the stage idles on a loop. Space or tap replays it.

Feature example

Sprite Shaders

Four project WGSL sprite shaders side by side: a pulsing outline, a dissolve, a hit flash and a wave. Scripts drive the burn and the flash through each sprite's shader parameters; Space flashes.
