Sorry just noticed your answer now.
Your game seems correct. I found a lot of them on codecanyon similar to yours, except you have a tutorial and the leaderboard. You should defitinitvely put it on codecanyon, I'm sure you would sell it.
For now, I focuse on others projects I have, but around the end of the year, I'll come back on this project and probably will contact someone (like you, why not...) to prepare me a full template very similar that I had already had in my Unity game, and so pay a little more.
So i'll keep your infos and your name, and maybe will contact you in some months.
Good luck with your template
