For a dungeon crawler, it's very comfortable. There's no gameover or penalty for losing battles. Shortcuts are frequent, you're not able to grind out an overpowered party (though how you play can easily make most of it a breeze), and there's a simple enjoyment from exploring to fill out the maps and item logs.

Finished in a bit over 10 hours. Party of Warrior, Wizard, Sorcerer. The lack of punishment meant I didn't care about healing (you also heal up anyway after combat). Had fun with a tank and two somewhat glassy cannons.
