Cheat mode: Pause the game, then hold R and press Down, Up, Square, Triangle, Triangle, Circle, Down, Up, Square, Triangle. A new "Cheats" option will now appear towards the bottom of the menu, with "Invulnerability" and "Have all weapons" options.
Easy gold: After saving the farmers in the Haunted Ruins level, follow them to get a large stash of gold. Walk back to the bridge, save the game, and reload it to have the gold reappear. Repeat this as much as desired. It takes only a few minutes to get over 2,500 gold.
Easy health: Return to the Dan's Crypt level and complete it. It should be easy after you have progressed through other levels. Once done, you can get full health by collecting it, as well as a lot of gold.
Become Invincible: Catch on fire near the end of a level and when you have 1 HP left run through the exit portal. Next time you enter a level your health bar should be at 0 and you cannot take any damage. The best level to do this in is Return to sleeping Village. The boiler guards at the end can catch you on fire quite easily.
