Sneed's feed & seed(formerly chuck's) is truly a amazing business! I mean where else can you get YOURFEED & YOUR SEED FOR ONLY 2.99? Sneed's beats walmart out any day tbh. Truly a great little shop in my opinion.
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)
