progressed through other levels. Once done, you can get full health by collecting
it, as well as a lot of gold.

stash of gold. Walk back to the bridge, save the game, and reload it. The gold is
now back for the taking. Repeat this as often as desired. It takes only a few
minutes to get over 2,500 gold.

If you have only one HP, catch on fire near the end of a level and  left run

through
the exit portal. Next time you enter a level your health bar will be zero and you
cannot take any damage. The best stage to do this in is Return to sleeping Village.
The boiler guards at the end can catch you on fire easily.
