Spelunky Classic HD HTML5

Web version of Spelunky Classic HD.

This version was built by targeting GX.games (not HTML5) in GameMaker and then modifying it. Essentially, it's a WebAssembly app, which means it should perform nearly as well as a native application.

It is available as:

• PWA (playable online or installable as a standalone app)
• Electron app for Linux, macOS and Windows
• Cordova app for Android

Unless there's a specific reason not to, I recommend using the PWA version. More usage info can be found here. Non-PWA builds may not be available in the future.
