I think you misunderstood what my comment was stating. By polishing this up I meant completing this for production (if that is what your intentions are). For example, more levels. My game too has a lot of work if I want to actually try to publish for sale etc.
Again, I loooooved the aesthetics to this game. I am assuming you created the assets yourself except for the font. I am really digging your art style.
Keep up the great work!
