First bug: I'm in free-look mode (mouse to look) and every time I save, the menu closes and I'm left with a pointer on my screen, can't look around with mouse. I have to load the game I just saved to get rid of this problem.
Second bug: I hit a bat in the huge room with all those stairs (after the first archer) and it just fell through the floor? It didn't die
Third bug: I try to rest, but it says enemies are nearby. I explore a bit, no enemies. I have to retract like 10 rooms before I can finally rest. A rat behind a door perhaps? Why should that impact if I can rest or not? Is my character really a scaredy-cat?
All in all, this is an awesome game! I actually jumped when I looked around in a room I just cleared and finding a skeleton warrior behind me. He came in from another door. Sheesh! Even doom 3 didn't give me this scare lol
