About this build

Not a game yet: the proof that the engine renders the way it must on the handheld. A scrolling gradient, two hundred alpha-blended sprites, a solid box, a 440 Hz tone while A is held, inverted colours while B is held. The same C file runs as an ARM binary on the Miyoo Mini Plus and as WebAssembly here.
