I've probably put 40 hours into it and never finished it - the lack of variation in the environments means I rarely play for more than a few days at a time, even though I love it while playing it.

Then I go away for 6 months to play other games in my catalog and cycle back, start a new party since I can't remember what secrets the old party found/hadn't, and rinse/repeat. Next time I'll have to remember that I don't want an Earth mage.

Still, for $3, absolutely, there's plenty of enjoyment to be had if a classic dungeon crawler with pretty light RPG elements is your thing, whether that's beating the game in one fell swoop or just jumping in with a new party configuration every now and then for a few hours of distraction between playing other games.
