TH08 Web brings the original Japanese bullet-hell shoot 'em up Touhou 8: Imperishable Night to modern web browsers via a source-built WebAssembly port. Developed by N0zoM1z0, the project compiles the reconstructed C++ game code to run directly in the browser while utilizing a custom WebGL 2 renderer and Web Audio integration. The entire game is playable from title to ending, including replay recording and browser-local saving.
