Delve!

Yes, this is a choose your own story... but it's also a dungeon explorer. The options you choose from are just related to defeating the monsters and making process towards the bigger prizes and even bigger monsters. If you're looking for an involved story with character development, this isn't the story for you (unless your mind wanders a lot while killing things). But if you want to hack and slash your way through hundreds of monsters on your way to glory, this is where you want to be!

Delve is something you expect to see on a website full of flash games, and it's that one dungeon crawler that you just keep coming back to, just to explore more.

Except, it's not a flash game.

This was written in the CYS editor, with scripting to get it's "game" aspects. The editor and scripting are all more or less basic. There aren't many things you can do with the editor.

Aside from the limitations, delve is amazing on it's own. It's got hilarious description, actually interesting battle scenes, etc.

Highly recommend.
