This is certainly something that can be improved upon post-jam. In fact I hope you do. Add more levels and mechanics as well as a story, then it might be a product worth marketing :) Now you probably already aware that its not original, but don't let that discourage you. Very few games come out that truly offers something original. Instead its different takes on old mechanics. I hope this helped.
