a theme based on the Nintendo DSi. done for now but I have some new Ideas for another version and ill be working on it when I have the time^^each month has its own color and picture. (see preview)here is a full preview^^
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)
