Shadow Crawl

- Added 5 progressively harder levels to crawl through - Level 1 "The Dark Passage": 9 guards with moderate patrol speeds and plenty of shadow cover - Level 2 "The Sewers": 11 faster guards with more lit corridors to cross - Level 3 "Abandoned Lab": 13 guards on a larger map with significantly more exposed areas - Level 4 "The Compound": 15 fast guards patrolling a sprawling, heavily lit facility - Level 5 "The Gauntlet": 23 elite guards at top speed with very few shadows to hide in - Reaching the exit now advances you to the next level instead of ending the game - Score accumulates across all levels — conserve ammo and move fast for a higher total - Brief transition screen between levels shows the upcoming challenge - HUD now displays current level number - Death screen shows which level you failed on
