The most difficult game I have played

Devil May Cry 3 is an amazing game. Its story and cutscenes are spectacular and I enjoyed every minute of them, but it was a very difficult game for me.

There are no checkpoints. If you fail, you do the whole mission from the start. Some puzzles were challenging -which is a good thing- and others really frustrated me.

What frustrated me the most is the Cube Chamber in Mission 17.

Also, when an enemy attacks you YOU GET HIT there's no avoiding an enemy attack. I had to repeat many missions during my first playthrough.
