It has lots of graphical glitches, but I haven't run into many gameplay glitches. When turning, I can see things render, which is annoying and kills immersion, but it doesn't affect the gameplay at all. I have also seen a character walk into a room twice in the same cutscene a couple of times. The frame rate drops significantly sometimes, but only for a few seconds. The game isn't well optimized, so the average frame rate is lower than it should be.

I've had zero crashes. One time my controls in the menu stopped working, but I could still play the game fine. Once I restarted the game, the menu controls returned to normal. That's probably the worst glitch I have seen.
