about

nx_wasm_shmup.nx -- BROWSER-PLAYABLE sovereign Shoot-'em-up: BASE-RELATIVE integer core, the SAME code runs native (base = a real mmap -> render a frame to PNG for eyeball verify) AND in the browser (base = 0 = our sovereign WASM linear memory). NO float, NO JS logic, NO 3rd-party canvas drawing. Real-time: the shim's rAF loop calls tick(input) every frame with the held-key bitmask (1=left 2=right 4=shoot); the core moves the ship, fires a bullet, advances it, kills descending enemies, respawns waves endlessly, and game-overs if a wave reaches the ship line (shoot restarts). HUD score drawn by our OWN font (no JS/canvas text). init()/tick(input)/render()/score()/ww()/hh()/fb_off() are the wasm interface (auto-exported by nx_wasm.nx). license_tier: ORIGINAL
