My first release, I always wanted a scale program without going into WiiFit all the time going through the Body Test. So I made one! and I added the Center of Gravity (COG) feature also. Hope you enjoy.
I don't have a wii u anymore to test it myself, but if homebrews are not visible on the wii u menu I think you can press L + R + minus to open the plugin menu, there should be an option called "homebrews on wii u menu" or something similar
Or when your player dies, you can say in code, if enemy exists, do nothing, but if enemy does not exist, then create enemy at certain spot. (This would be a pain tho for lots of emeies)
