Like with most games, the difficulty increases as you progress, so it's normal to feel like the game is getting more difficult as you progress. If a level seems much too difficult, it's a good idea to take a step back and upgrade your characters to make them more powerful before taking it on again. Below are some of the ways to do this:
- Spending Gold to level your characters up. Remember that each character can be levelled up to match your current player level, which you can see at the top left of the screen.
- Using shards to Promote your characters. Need more shards? Try replaying older missions to earn shards for specific characters, or - if you've already earned 3 stars - look the level to quickly gain shards! You can also spend diamonds in the shop, or Arena or Survival tokens in their respective stores to buy shards directly.
- Upgrading your characters abilities using gold to increase their effectiveness.
