let get the challenge started ⭐⭐⭐⭐⭐

The Possessed Login is a perfectly normal sign-in screen, until you use it. The show-password icon is a real eyeball: it follows your cursor, blinks, and squeezes shut (blushing) while you type your password. Reach for Log in and ghostly hands drag the button away ("Catch me!"); on the third try it gives in. A wrong password makes the screen shudder, the CRT glitch and ACCESS DENIED drip down in blood, with a taunt that gets more helpful every time. The secret is "trick or treat": the glass cracks and a glowing jack-o'-lantern says "Come in. Don't look behind you."

I was in the developer's seat and used an AI coding assistant for support: the scene is built with the Rive CLI in RML, and the behaviour is Luau scripts driving a five-layer state machine through data binding. For the atmosphere I used two custom WGSL shaders on GPU Canvas: fog lit by a candle that follows your cursor, and a CRT overlay with scanlines and glitches. The touches that are entirely mine: I wrote all the jokes and taunts myself and recoloured the palette by hand in the Rive Editor.

Try it: the password is "trick or treat" (try a wrong one first).
