The voice acting was great, though it was a bit too low compared to all the other sounds in the game. The inverted controls (mouse vs wasd) worked surprisingly well IMO.
One minor issue I found was the lack of sound cues from the monster. Multiple times, I found dying out of nowehere. Additionally, I couldn't quite grasp why the camera failed to make the monster disappear half of the time.
Overall, it's nice game!
