Run endlessly through the dark catacombs! Up/W/A button = jump (double jump available). Down/S = duck to avoid falling rocks. X key = attack nearby enemies. Avoid pits, spikes, and crumbling floors! Collect coins (🟡), health orbs (❤), gems (💎), and power-ups (★ - invincibility or magnet). Chain kills for combo multipliers! Speed increases with distance traveled. You have 3 lives - survive as long as you can! Look for lanterns in the darkness.
