Increase Game Downloads and Active Users

Hi

I launched my first game on the Google Play store Sponge Dodge(I can't put the link because imma new user ). I am just 16 and don't have any marketing plan to increase the downloads or active users. I have done promotion on social media and earned about 40 downloads from that and about 10 more by sharing it with friends and family. I have also localised app description with proper keywords.

Please help me in the marketing side of my game by providing tips and suggestions from your experience and help me increase my downloads!

And please make sure to try my game once !
