Well, I purchased this game last week, And I've thoroughly enjoyed it. I've encountered numerous small bugs, but no crashes yet. I have yet to get past the moathouse as I restarted in Ironman mode, and I'm back at the moathouse.

My main complaints have been the lack of solid documentation.
It shouldn't take 15 minutes of frustration to find out that you click on the tiny yellow plus sign that appeared above the character potrait to level.
Cure spells shouldn't be buried deep in the text far away from descriptions on spontaneous spellcasting.
I have yet to work out how to apply my metamagic feat to the spells.
The interface can be rather clunky at times: Selecting a spell to memorize can require several attempts to place a spell in a slot. Also as a specialist wizard, you need to re-memorize your specialty spells every time you level, as it is those slots which apparently become free each level.
In Ironman mode, the "Save and Quit" selection does nothing, while the "Return to Game" saves and quits!
I also experienced some strange calculation of Skill totals: at 3rd level , cross class skills only granted 2,5 ranks, inspite of having placed 6 skill points into those skills.
