Dungeon Where Nate Explores Rooms, Finds Keys,

a dungeon where Nate explores rooms, finds keys, unlocks dash slash, and fights a shadow boss Build this for Nate: quick Roblox/Minecraft energy, not babyish. Make one complete browser game with working controls, visible goal/progress, challenge, win/loss, restart, touch support, retro Web Audio, and one useful upgrade/resource loop. Include PALETTE, SPRITES/PIXEL_SPRITES, drawPixelSprite/drawSpriteFrame, drawPlayerSprite/drawEnemySprite/drawPickupSprite/drawHazardSprite, particles/spawnParticles, floatingTexts/addFloatingText, TUNING, ROOMS or WALLS, KEYS or LOOT, DOORS or CHESTS, GUARDS or ENCOUNTERS, HAZARDS or TRAPS, and UPGRADES. Do not add towers, protected cores, base health, repair/build/place controls, WAVES, ROUNDS, currentWave, finalWave, or Wave/Round HUD labels unless the prompt asks for them. Title thumbnail must be scene-first: colorful zoomed-in action art with standard text zones only: title top-left, start top-right, Objective bottom-left, Controls bottom-right. No paragraph instruction card, no large opaque text panel. Finish the complete HTML with all closing tags. Prefer 500-750 reliable lines over a bigger unfinished game.
