Yooo!!! I like it! It was challenging but I got to level 19. At first I was getting to level 4 and dying but then I figured out the space bar. Hint hint... I want people to figure it out. It became more easier and balanced. I was then using it as a tactic to flee(Hint hint...). It makes you want to play more of it. Stick with the idea that your blood drains over time but make it so that it's less for casual gamers. I feel like this is for slightly hardcore platformer game just to beat the highest score. But it could be good to. Just think about who you're targeting either casual or hardcore gamers. I would like the vampire to emit some kind of blood ability that shoots the knights and kill them. This is because at the start of the next level I was already dead because they huddled up on me. But I made it to level 19 yeah!
