Ooh, I really like your implementation of the lethality of blood limitation! The blood maze feature is very interesting! The maze itself was a little on the small side for me because I at first really started to panic with the quickly-approaching vampires (haha~). Still, I really enjoyed that on-kill blood maze mechanic, it felt like their revenge for us slicing their heads off, hehe! On a related note, I also really liked the visuals (the cutting animation especially is really nice) and the UI, it feels really clean! Nice job!! ^^
