The game is decent, but suffers from a lot of problems.
It is way too easy. Even on the hardest difficulty, it is still easy.
It is too short. It has extras to keep you entertained, but the game is still relatively short for a diablo clone.
No multiplayer. I have no idea why, but it lacks multiplayer entirely.
And there is a lot of really bad, or just poorly thought out design choices (an example is the equipment you start with is the best in the game, just keep enchanting it, enjoy having a set of equipment with +1 million to all stats).
All in all, it is a decent game and worth the price. But just don't expect it to be as good as other similar types of games.
