I like it! Very aggressive deer. It seemed a little too aggressive at the beginning. Maybe you could make it start slower and get more aggressive the more car parts you collect.
The only other thing I can suggest is let all the car parts exist at the same time. Having to collect one to spawn the next feels a tad confusing and even a little unfair. "I already looked over there it won't be there." was a thought I had.
You nailed the creepy vibes tho, well done!
