Yes it is easy on the "Normal" setting but there are 2 harder levels if you want the challenge - basically you get more monsters.
My main gripe is that there isn't much strategy required for battles, you basically keep whacking or zapping until you win, which you will, esp if you save regularly and can restart on the odd occasion you decide to preserve your potions.
Otherwise this is a basic dungeon crawl in the aforementioned eye of the beholder vein, but you find yourself wanting to complete each level, find all the secrets and kill all the available monsters to get the extra HP.
And before you know it you've finished.
Yes it's too short, too easy, but fine fun whilst you're at it...and you can get it a lot cheaper in second hand shops than amazon are selling it for.
