Your profile says you are a very experienced programmer (7 years under your belt) but all your games are a little too simple. If you truly have as much skill as you say you do, I suggest you hunker down with your next project and take your time with it. Plan it out, polish the art, polish the code, and release something amazing!
Don't get me wrong I'm not bashing your games. Nothing wrong with simple games. My games prove that (although I've only been learning to program since the start of the year...). I actually liked the concept of this game. Heck I feel a bit inspired haha
Take your time with your next project and it will be sure to shine. Best of luck!
