Pixel Art Action Roguelite Game Builder

Build a 2.5D pixel-art action roguelite in one HTML file with Claude Code. Fast sword combat you can read: every attack flashes yellow (parry it) or red (dodge it). Combos, launchers, plunges, dash thrusts, charged slashes, ripostes and a Blade Storm finisher. 18 rooms over three areas, 8 enemy types, 3 bosses, 24 upgrades, real 3D lighting under hard pixels, rebindable Steam-style controls and a synth score the effects play in key with.
