Most actually think it is far to easy, but yes it is a little difficult in the beginning of the first act. If you find it too difficult my suggestion would be
1. Find the first battlefield key
2. go there and kill of some weak enemies and accumulate some gold
3. buy new and better equipment from the battlefield merchants. They respawn every time you leave and enter again so just do that a few times until you find some good equipment.
4. save often
5. have many health potions at hand
6. use pause during the battles

If you do one or more of the above you should have a reasonable easy time getting through. And very soon you too will be complaining that it is to easy <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
