This is a game idea that has been knocking about in my to-do list for a long time, and the Rive Halloween challenge came at exactly the right time to finally make my ultimate pumpkin carving simulator. I took great care to balance a realistic look with stylized graphics, and to give players enough tools to express themselves without overwhelming them with a full-on sculpting suite.

Built with both the Rive CLI and GPU Canvas. The scene is written in RML with a coding agent through the CLI, and three WGSL shaders render the 3D pumpkin: carved relief, cut walls, candlelight glowing through thin flesh, light shafts and smoke. Luau scripting runs the carving, undo and falling pieces, with data binding and a state machine driving the controls. I made a post on my own website detailing the creation of this game ! https://www.sagitsoftware.com/projects/hollow/
