I played as a mage on moderate difficulty, leveled up to 14, worked my way down through the levels killing everything. Then I opened a door on level 10 and Lord Dredmor was in a fairly pathetic group of mobs. One curse, a few fireballs, and 1 teleport later, I beat the boss of this roguelike. Then my game crashed to desktop. Is that really supposed to be the end of the game?
Well, the crashing probably isnt supposed to happen. With a game like this though, you havent REALLY beaten it until you've done it on the highest difficulty with Permadeath on (unless that is, in fact, what you did.)
I'd say you haven't REALLY beaten the game unless you've beaten it: -Going Rogue -Permadeath -Choosing NO skills at all (if this is an option)
As far as I can tell, you can't start the game without using the 7 points. Though I wish you could get more than 7 skills total. Having all of them would be nice. LOL!
I do believe the game forces you to choose all 7 before it lets you start. Makes sense. It'd be like Nethack or whatever letting you choose NO class before starting, otherwise.
