Thank you! When I revisit this project for future development I will definitely add some form of visual feedback but it was my intention that the player would have to gamble a little on when to stop drinking blood (I was thinking of the scenes in the Interview with the Vampire movie where right after Louis and then Claudia were made vampires, they had trouble knowing when to stop feeding). I might also add this as a perk for leveling up the vampire that you get better indications of when to stop.
