GAMESLASHGorest
By Heroza / Gorest
2D scene and spritesheet workspace with editable layers, motion previews and a Codex-assisted local authoring workflow.
Follow the official README to run the local app with Node.js 20 or later. Create a scene, arrange background and character layers, import or generate sprite sheets, set clip metadata and preview movement before saving. Codex can help change scene data and the application. This supports prototyping, not a guarantee of a finished game; review animation quality and any generation-service requirements. Code is MIT-licensed, but The Horror Notes artwork by Heroza is demo material under a separate asset policy, not a free asset pack for other games. GameSlash reviewed documentation and official images, not a runtime test.
