I stumbled on this earlier today on japan probe and it is freaking wicked. http://babarageo.com/flash/ginormo/index.html
You play as a weird pink wiggly guy with a sword. The whole game is controlled using the mouse move the mouse to move the pc and click to attack. You move around the map getting into battles and fighting bosses. After beating the first boss you get to move to the next square on the map. As you progress you'll find shrines which increase strength, intelligence, and vitality. As well as a blacksmith that increases the size and thickness of you sword. You'll also come across magic shops and armor dealers.
The game has an auto save feature so you can continue from where you last left off. I'm currently on the ninja boss. The game is pretty intense, enjoy.
