The enemies are very often shooting garlic from outside the screen. I walked close to the vampire and therefore had my camera there but the enemies saw the vampire when I couldn't see them. You cannot jump in front of the garlic to save the vampire from 1 healthpoint so if you did not see the enemy and he shot correctly there is nothing you can do. Also sometimes the enemies spawn like 2 meters away from my character and shoots immediately. However, with this being said I still managed to win the game on my first attempt. The idea is but I think the game need some polishing. Music was good and the hurt sound for the vampire was funny.
Thank you for the in depth feedback, well I think it was intended to make the enemies shoot from big distances. I don't know why, but I always end up making hard and frustrating games. Glad you were able to beat it from your first attempt!
