So, this is one of my first skins. Still looking very nice and all, it is based around the 13 episode anime "Spice and Wolf", which happens to be a favorite of mine. Color scheme goes pretty well together, and text is easy to read.
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)
