Gravity-driven side-scroller. Think Shovel Knight, Cave Story, early Castlevania. The key visual signature is a rich multi-layer dungeon/forest background combined with detailed character sprites and environmental hazards.

Level layout: tall vertical world (20-24 wide, 28-36 tall). Platforms at varied heights. Spike hazards on some floors. Secret alcoves. Camera follows player in both axes.
Always use bg-artist with --theme dungeon or --theme outdoor-night. Apply scrollFactor: 0.25. The dark, atmospheric bg is essential for the visual identity of this genre.
