Excellent game, very creative.
Possible Improvements:
- Turning off the valves could require moving in a circle around them (like the curtains)
- Unique death animations for the count would be fun (I intentionally let him die to the mirror because I wanted to see how "no reflection" would kill him)
- Breaking the mirror with the garlic was hilarious, but it would make more sense to use the candlesticks
- Ensure that holding directional keys as you restart allows you to immediately move
- Apparently some versions of vampires have the obsessive urge to count things (hence Count von Count), so throwing a bag of rice on the ground in front of the Count could be a stalling mechanic for later levels
