You're pretty good.
You're very good at game design. Your art style is very sketchy but it works well enough. I agree with popular opinion that a story would accompany this game quite well.
You should only be working on your game design. Forget the art and forget the story, you could be really good at game design if you keep working on it. let other people handle the art and story, collab someone if you want, but keep on that game design track. It's inarguably the most important part of a game. But of course flashy lights sell bigger than any kind of substance.
