Hi amazing person im JamesxGamer im a big fan of your work i see you are doing a project on [Project] Spice and Wolf DS Translation i wanted to see if i can help out anyway. I speak japanese and english. If you need any help just let me know
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)
