The idea of this game is undoubtedly great but the overall structure of this game is not appealing, first, the graphics need to be something good, then the controls of the game should be awesome enough to play and enjoy. The overall concept seems to be great which upon implementing nicely can turn out to be really awesome game. So you can try scaling this game up ahead of time and make something out of it. All the best, I would love to check the future progress of this game and other games that you make.
