Summoner is a spooky capture game set in a haunted graveyard. Zombies, ghosts and pumpkins peek out of their hideouts for just a moment: catch the ones your recipe needs before the hourglass runs out, and each one rises through a summoning portal in the ritual circle. Much of the art started as hand drawings.

Features used: both CLI and GPU Canvas.

• Rive CLI: I built the prototype and MVP with the CLI (scene, Luau scripting, data binding, verification and screenshot tests), going back and forth with the Rive Editor for layout and visual polish. • GPU Canvas: almost every effect is a WGSL shader running inside Rive: the ritual circle and its sparks, the capture bursts, the summoning portal, fog and candle light, fireflies and paper-cut confetti.
