If you do play it, just avoid falling in the bottomless pit in the catacombs about 1/4-1/3 of the way through the game. It is the source of 2 different game breaking glitches; mine and other one traps your character in the bottom of the "bottomless" pit.
There is one other game breaker and seems to be completely random, but the game won't progress past certain bosses later in the game. Its completely random from what I have seen though as to what causes it. Seems to happen more frequently on subsequent playthroughs though.
