Not much to do here but kill or be killed.
Considering it's based off another game.
A lot of space to move around in so it is difficult to get yourself cornered.
Which is okay by me.
I was able to save so many powerful items which made the ending too easy [ie Conduit, Storm Ring, 3 Flamitts] also game ends in a dead end which isn't too good.
I would have to say the battles. I also liked the map that came with the download.
Not about the dungeon: The fact that I have never played Diablo means I couldn't make any comparisons and therefore my rating might not be as accurate as it could be.
About the dungeon: I usually don't like dungeons where I can only pick one person, the fact that there were only three champions to pick from, and lack of chests. However that's probably how the Diablo game is. As well as the fact that the only thing you really had to look for was the stairs down. Once I found them, I stopped exploring the level I was on and went down.
