Tips for a successful adventure: 1) Choose your kills wisely. If killing a monster serves no purpose (that is, getting treasure/closer to the stairs/etc), then don't. 2) If you have to choose between gold or a treasure chest, take the chest. 3) Health potions and/or the heal magic will save you frustration. Invest in both for a long career as a dungeon diver. 4) Get as far as you can before using the Escape Wings. Your health makes no difference once you've escaped, and that next chest may have a health potion in it.

This strikes me as a flash version of the XTreme G series for the N64 and Gamecube. Good attempt, but falls a little short, since it gets very repetitive after a little while.
