Hello everyone

I made a transport tycoon game a long time ago https://play.google.com/store/apps/details?id=com.MagicHero_games.Transport_luck , but the game is not very popular.
I would like to understand what can be improved so that more players play the game? I have already added a lot of different elements to the game. And the game process itself is varied. For example, the speed of production of goods is affected by:
- basic speed of product production
- improvements in the place of production
- improvements of the city to which the production is attached
- manually activated bonus for half an hour
- improvements in the laboratory
- bonuses from special cards
- bonuses from the quarterly newspaper
- bonus from the headquarters
- from additional buildings in cities
- efficiency of production from electricity
Negative reviews are mainly due to the lack of translation into other languages ​​(Portuguese, Italian, French, Spanish).

Thank You
