MAKE THE REVENUE MUCH BIGGER. People are uninstalling this game, aren't you concern? It's fun and all but it's hard to earn money. You say get keys to unlock chests HOW COULD I WHEN I CAN'T EVEN PASS A LEVEL WITHOUT THE UPGRADES. STORIES AND CUSTOMER PROFILE ISN'T HELPING EITHER. Now, change SOMETHING or people will hate your game. Looks like this game is for people who purchases in games 🙄.
