I encountered a game-breaking bug during my first play through of Act 1, I thought it was my fault or sth making me run around the place aimlessly in search for other alternatives until I turned up to a walk through video just to know that my game was bugged. When the hairpin was inserted into the lock it just disappeared into thin air, preventing me from using it to unlock the door to the warehouse. Thankfully that I only had to load my save and try it again. There's also another annoying bug that is I didn't get the achievement upon encountering the mockers. As a player who likes to 100% game this is a minus point from me. I also have seen reviews saying that the bugs get worse in act 2 so I might as well just put this game on hold for about 1 or 2 years for developers to fix things up.

Edit: I'm in the middle of the last part of act 1 and I must say this is THE MOST ANNOYING CHASE sequence EVER. I am supposed to be on an adrenaline run from the monster and guess what, ROAD BLOCKAGES LITTERED ON MY RUNWAY. WHY THE HELL DO I HAVE TO MOVE BOXES TO FILL IN THE GAPS? Imagine sprinting and having to stop to ♥♥♥♥♥♥♥ light the black patches on the ground. The lil monsters, ♥♥♥♥♥♥♥ lil monsters, lil ♥♥♥♥♥ that prevent you from moving your boxes and make you late for your delivery date and THEN you got strangle to death by your boss of a monster. I'm THRICE the SIZE of that lil ♥♥♥♥, why can't I kick its ass into oblivion?
