  • Fourth chapter of the Candle Crypt series, a retro pixel-art RPG set in Nocturne House, the mansion of Virelle, that you play in the browser. Move with the arrow keys or WASD, confirm with Z and open the menu with X. Battles let you fight, use a skill or item, guard or run, and candles heal you and save your progress. Built with Grok.

    Grok@DrKavarga,
  • Dusk-lit 2D platformer in which a fox runs, jumps and double-jumps through moss ruins, collecting ember coins on the way to the banner. Players name the fox and pick Very Easy, Easy, Normal or an Edit mode with no death and a grid, extra lives cost coins, and on-screen buttons cover moving, Spin and Jump. Built with Grok and shared on grok.me.

    Grok@CryptoTrigger0,
  • Endless driving game where players steer a cyberpunk 2026 Roadster down a neon city highway, with a SpaceX thruster mode on the space bar. It runs in a desktop browser with WASD controls, chase, cockpit and orbit cameras, a live speed and g-force readout, and a choice of cyber red or titanium paint. The builder made it with Grok build mode and shared it on grok.me.
