My huwaei g6 is not turning on?

Last night I just played game called tiny troopers!! When I realized that my battery was just 9% then I immediately charged my mobile and went to bed!! In morning when I woke up and look to my phone , the charge lid was just blinking red(twice and a gap) and when I pressed unlock key it wasn't charged (only a red indicator of charging was showing). I tried to switched on but it didn't boot up (showed only low power red battery icon). What should I do ? Please review it !! It would be great help :)
