On the left is a continous blood effect which could be displayed when the character is low on health but it looked weird. On the right is a burst of blood that only appears when the character gets hit. I also changed the shape so it looks more like droplets than just circles. The blood effect was an idea by a friend that I thought would not fit well with the game graphics, but I made it cartoony and it ended up looking pretty decent and somewhat comical. This was actually a very interesting suggestion.
