Game Lifecycle Model

So, there i was, thinking about my game lifecycle model and drawing this:

This would be a perfect cycle as i see now, releasing a game every month. At first, the development time might be longer, as i am still learning libgdx. Then, i should concentrate only on important stuff. 25 days should me more than enough to create a simple quality game. Keep in mind that Flappy Bird was created in 3 evenings after work, thats the type of games i will be concentrating on : simple, easy, fun casual games.

P.S. this is for a hobby-like project, with time spent after work at evenings!
