I like it, it was pretty fun. At first I thought the jump controls will be annoying but they are actually pretty clever and fitting the vampire theme. The wall-jumping could be improved though. I was able to do it but didn't really "got it".
On levels 9 and 10 there were excessive blood fountains, I didn't need all of them. Also I wasn't able to finish level 11, the one with 3 different bombs. It was just too hard for me.
I wish the timers on bombs were more polished. They could, for example, beep and blink faster and faster before they explode!
Overall pretty cool game!
