Is there a roadmap for this project? What is the goal here? Have you planned and mapped it out yet? Not trying to sound rude or anything, just wondering. It most likely is your first attempt at game development, so respects to that.
I generally think that the most important thing in the process of creating a game, is to know what you want to make. Then start focusing on the gameplay aspect and making sure that the mechanics are just right. It is very important in a game where the gameplay features more than just pointing and clicking with your mouse, that it gives off a smooth and satisfying feel, and works as intended. Most of the time, it might just be the format of gameplay that doesn't particularly give a responsive result.
I don't necessarily have a particular point in this comment, other than that I think brainstorming and thorough planning of a project is what makes or breaks a game in the end.
As for your game project as it stands now, it isn't bad. If you are serious about this, then keep going and keep improving. You definitely got the creativity for it. And to be honest, in my humble opinion, I think art/graphics comes in second when creating a game. If the game has good gameplay and a satisfying format, then the quality of the art isn't as important to me. Always good to find a perfect balance between quality and quantity. At least, that is what I think.
Anyways, good luck with your project, and keep going. Cheers!
