As an update, I'm playing around with ways to make the heart particles spawn. So far the only way I've found forces the mod to be client side as well. If I can't figure out another way I may release that as a separate download option.
Outflow Gaming Network noticed your mod and we give it a 10/10! We've just finished a little review that can be seen below. It would be appreciated if you could use it along side your video in the main post!
