You should just go inside and test it out yourself. I'm not really going to put anything; I don't wanna ruin its natural beauty. Use the "HP Updater" Event block, it's what connects it all. The variables are self-explanatory. (maybe)
Made with 152 blocks, 9 scripts and 1 sprite. Assets ripped from The Spriters Resource Thank you for the support I got yesterday. I decided to make a new version. Still completely Free To Use.
