 If you hit a spiderweb, a spider spawns, and you are slowed for 15 seconds. If you are invincible, you are not slowed, but the spider still appears.
 Running and jumping both move you at 1.5 your normal speed.
 Items bounce away from you when they are freed from the coffin. You must jump to catch them when they are in range.
+You can switch between weapons you've collected using the number keys (1, 2, 3). This allows strategic combat - use different weapons for different situations based on their damage, range, and speed.
 The game automatically saves your progress when you have collected 200 bone dust. You will hear a message saying the game has been saved, and a wolf will howl. To load a game, use the load option in the main menu. Load only appears if you have saved games. The first save should happen around level 6.
 
+Game Modes
+
+Story Mode: Traditional level-by-level progression through predefined stages. Your progress is saved, and you can collect extra lives by gathering bone dust.
+
+Survival Mode: An endless challenge where you face wave after wave of increasingly difficult enemies. Each wave gets progressively harder with stronger enemies, faster spawn rates, and longer levels. In survival mode:
+- No saving or loading - each run is a fresh start
+- No extra lives are awarded - you rely on your starting lives only
+- All enemies use aggressive "hunter" behavior instead of patrol patterns
+- Each wave must be completed by defeating all enemies before you can advance
+- Bone dust still provides health bonuses but gives bonus score instead of extra lives
+- All coffin contents are randomized to ensure fair gameplay
+- A detailed statistics report shows your performance at the end of each run
