By the way, for anyone wondering how long it takes to beat the game (i.e. kill final boss and unlock debug mode), I was able to finish it in 2 hours 41 minutes without using console, bugs, or exploits.
If you want an easy vanilla path, here's a mini-guide (and I'm sure someone could optimize this):
Run a mix of Bust and Size. Scrounge up 200 gold around town, then go into the tavern and grab Solon (the big purple gal with the throwing knives).
From here, prepare yourself and do either Sewers or Lich Dungeon. Stay in the dungeon until you find the root and pull the nail out, AND Solon reaches 10 affection so she won't leave. Get the blacksmith key from near Lich Dungeon and grab a magic rod from the blacksmith. Prepare yourself again and go to the Docks, fight through to the dude at the fence and jack 'em for his Dock Key, then use the Dock Key to unlock the back gate.
Look around for some bright red crystals growing out of the ground, because there is a guaranteed Red Hot Fetish, the most overpowered weapon in the game.
Pick it up and then go to the bridge, down into the mines, and into Crystal Cave, because essence drop rates are highest down there. Kill stuff until you reach about 200 in Bust and Size from essences, then leave and run to the Final Dungeon (go towards the tower, enter the bamboo forest, hook a left somewhere, down onto the beach, through the cave, fight off the bunny, and there you are).
Pick up everything you see, and feel free to leave and save on any floor. You should find a lot of essences and pure metals here, which you may want to take back to town after a few floors, but you are probably powerful enough at this point to kill the final boss.
