As a vampire on your nightly feast, scare unsuspecting victims to increase their heart rate. The faster their heart rate, the more blood you extract in a single bite. Use your vampiric powers to terrify and trap your victims, but be careful... go too far and they will faint, and no self respecting vampire would feast from an unconscious victim. Where's the sport in that? Play it here: http://www.overworldlabs.com/ggj_harvest/Harvest.html
