About the project
Cave Story is Daisuke Amaya’s platform adventure. midzer’s NXEngine-evo fork lists a hosted browser build, whose landing page credits the original author and offers a roughly 9 MB load. NXEngine-evo develops Caitlin Shaw’s NXEngine recreation with SDL2 and other improvements; it is separate from commercial Cave Story+.
Technology: WebAssembly / Emscripten / SDL2 / NXEngine-evo

Before you play
The live landing page and author fork were reviewed; the game load was not started. Key bindings come from the fork’s source and are not a browser gameplay test. No browser gamepad, touch, save recovery or full-campaign compatibility claim is made.
Questions & requirements
Do I need game files?
The reviewed hosted landing page offers a prepared load with no local-file chooser. Original freeware Cave Story content remains distinct from the GPL-3.0 engine licence and is credited to Daisuke Amaya / Studio Pixel; freeware does not mean public domain. Commercial Cave Story+ files are outside this listing. No game data is hosted by this directory.
Has this build been tested here?
The linked author's documentation was reviewed on 2026-11-07. A complete gameplay session, save recovery and device compatibility have not been independently tested. Supported controls below are documentation claims.
Where do I get help?
Read the project documentation for build-specific limitations and issue reporting.
