It is a really good game and worth your money. There is alot of hacking and slashing in the game that is mixed with a briliant story line. The graphics are awesome. The full version I never had a problem with crashing. The quests are good. It isn't just a main quest that you follow but also sub quest that leads into the main quests. On the problem with the attacking just hold the ctrl button and your character will attack the nearest creature.
It was my money's worth buying it. And now I am addicted. I even gave away my diablo because Divinity is a great game.
I hope this helps but see for yourself
