Active Installs Dropping Daily

We have a game that drives around 300 daily installs when we first uploaded to google play.
A few months later, the daily installs dropped to around 200 but the active installs still managed to increase slightly everyday.
Recently, our game hits 36000 total installs but the number of active installs is dropping daily.
The game is currently driving only 80+ to 100 installs.
Does it means that the lifespan for this game is over?
Is there any way to save this game?
Does running campaign helps?
Thank you.

This is the usual trend. It will stabilize at a number say 80 and you will be getting that number of installs daily. On special days it might raise but will go down and will stabilize at 80.
