I played this with 2 of my friends, one a game jammer. We had fun killing each other. We would have loved to have seen some more graphics on your walls but we understand this is a game jam and there is limited time. There were a few quality of life things we also noticed. the game mouse lagged behind our actual mouse in quite a few instances and the sliders for sound and mouse sensitivity were not very responsive.
I really liked the fact the difficulty of the vampire changed over time. I kept hitting my push to talk which nearly got me killed as a vampire because it opens a window i can type into and therefore I can't eat my friends and taunt them at the same time. ^.^ We were basically useless as humans when we separated. but the moment we figured out team work we were able to defeat the vampire. I can see, however, the vampire being a bit op if the player knows what they are doing and you only have 2 people but I think that is a known difficulty.
Overall, I thought it was a very good job, especially considering the quantity of time it was built in. great job.
