Does this sound like a good video-game idea?

the game would be called リトルクラウド (Little Cloud).
wewe would play as a 12 mwaka old girl named モモキン (Kin Momo). it would be about her going all around tokyo and finishing her mission (be killed in honor of jashin). the gameplay is wewe walking au running around tokyo, getting to a very important alley. to get to the alley, wewe would have to go to the very end of tokyo and find a sign that says 蝶 (butterfly). wewe would go in, and a cut scene plays. in the cutscene, hidan would be at the end of the alley. he then says, "your finally here?". then kin drops on her knees and says "im ready. for jashin.". then a black screen comes on and all wewe hear is hidan killing kin.
