Well, after almost 3 years of not having a PC setup i now moved back out on my own and got my computer all setup so i can now socialize online normally again =D
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)
(Happy birthday again if you didn't see my facebook post)
