Need to develop an Android Game in 7 days

I want to develop a gaming app. It's inspired from Subway surfers and Temple run.. Firstly On clicking play button, 7 subjects option will appear. Gamer can choose any one subject. The main character has to run, cross obstacles and after a point of time, there will come a junction where 2 ways part.. A question regarding that subject will be asked at that junction, and the 2 options will be on the two ways of the path. On choosing, the correct answer, the game continues and on choosing the wrong answer, the player falls in a ditch. I this way, the game continues with the questions coming up at irregular intervals., till the highest score is reached..
