Allow me to be brutally honest here, before someone else crushes your dreams. The game's presentation (I haven't actually tried, I couldn't spare 5,66$ for it) makes it look like it's very far from being ready to be :
. On Wii U
. Worth 5,66$
I do not know if the gameplay is fantastic, because, again, I haven't tried it, but even if it is the case, maybe you should look into polishing the presentation and making better graphics for it. A teal sprite, a couple of pixellated fireballs and a black screen won't cut it.
Keep in mind my critique here is being made with the best intentions and might be useful for you as a reality check. Keep working on the game's presentation and it will eventually be worth the price you're asking for. For the moment, I don't see anyone, beside a couple of very good friends who would like to encourage you, buying it.
Good luck with your project and keep it up! Your graphics are actually decent and I'm sure that if you put some more effort into it, you'll make a game that looks, feels and plays great.
How specifically can the graphics be improved? As in: art direction, dimensional (2D, 3D, etc.), etc.?
I'm looking for people to help me with the art since I'm not artistic, but everyone is too busy to help me out. Even when I'm willing to pay for art.
In any case, thanks for the constructive criticism!
