Dungeon Nate Finds Keys Unlocks: Dungeon Raid.

Dungeon Nate Finds Keys Unlocks: dungeon raid. Vibe: not babyish, boss fight, hard but fair. Player: Nate as the main character. Goal: reach a clear finish objective. Loop: dash slash through enemies, collect resources, fight threats. Controls: move with WASD/arrow keys, use space/tap for the main action. Threat: a boss plus smaller hazards. Upgrade: keys that unlock doors plus a dash slash ability. Must include: dash slash ability, shadow boss fight, keys unlock doors as visible gameplay. Win/loss: win by completing the goal, lose when health reaches zero. Look: moody pixel dungeon with readable traps. Wow: a dash slash boss clash with a big visual burst. Build a complete Nate-ready browser game with touch, restart, visible progress, sound, one useful upgrade, one escalating threat, and one memorable wow moment in the first 30 seconds. 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, PLATFORMS or LEVELS, HAZARDS, and UPGRADES. Do not add towers, protected cores, base health, build/place controls, inventory, mining/breaking blocks, block placement, or wave-defense systems 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.
