Another skin from an unknown author; as always, if you know the original author, let me know so I can give them credit.Haruhara Haruko from the OVA FLCL. Nice and simple and it does the job. Grab it if you dig it.
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)
