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. One .riv file that plays on phone, tablet, desktop and pen display. Play: summoner.eduxdux.com (http://summoner.eduxdux.com)

I made a customizable animated badge in @Rive ✨ Rather than a single fixed animation, I built it as a small system that can generate different variations. The sparkles are also procedurally generated with scripts, adding a bit of randomness and life to each badge. You can play with it on my website ↓ https://eduxdux.com/projects/badge/

Cover image for Onboarding made with Rive I built
Onboarding made with Rive I built a weather app that compares three meteorological models, which can be pretty confusing if you don't know what you're looking at. So I made a cute little guy to show you around. He reacts, moves around and guides you through the first steps of the app. Just wanted the onboarding to feel a little more fun :) You can try it here: https://dux-meteo.netlify.app/

My entry for the Rive Game Challenge! 🚀 A fully functional 2D incremental clicker where you manage a grid, harvest resources, and automate an economy to fight a spreading virus. • Designed with a solid GDD for balanced incremental math & upgrades. • Grid Mechanics: Plant seeds & collect wood. Beware the dynamic "Rot" hazard that infects healthy tiles! • Custom AI (Scripting): Smart targeting logic. The Sower plants, Reaper harvests, and Slime hunts the Rot. • Economy: Reinvest wood to level up helpers for speed & massive Critical Hits. • Tech Stack: Global state script for grid arrays, Data Binding for real-time UI, and State Machines for seamless animations.
