The death sprite is funny, good job on implementing the main mechanic! I also like the character sprites and that they're little blorbo animals.
The music is a little bit loud on my end so you may want to look into making an easy volume slider for future games.
For the last level with all of the vampires in a party, I assume you wanted it to be easy for the player as a celebration right? Maybe having a one-way mirror object would be useful for that level because I died a lot of times trying to get past it.
Fun game!
