So it's a Puzzle/Reflexion game. For each level you have to shoot the target twice, using "quetzalcoatl idols" to lauch fireballs. These fireballs have to make their way through the level using different objects.
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
