So far it's pretty cool, but hard, they certainly pulled no punches. Very true to the older games it's based off, they even have a mode that disables the auto-map on your save so you have to use grid paper...I'm not there yet.
For $13 it's a great buy, but there isn't much story (not much needed really) and so far there's only one dungeon texture, I'm not really expecting much more. (game is 680mb total)
This game would be amazing on a tablet
