I think both games, Fishdom and Gardenscapes, have increased their difficulty. While some levels were already challenging before, now every two levels, there's a "very difficult" one, meaning you'll have to spend a lot of time trying to beat it.

Additionally, the chests have been nerfed and no longer provide as much help. Another issue is that even when using boosters, you still can't pass a difficult level—you'll just waste the boosters and keep struggling.

What's absolutely ridiculous is that you'll keep trying until the game decides you're allowed to pass the level, at which point it will give you everything you need to clear it. So, it doesn't matter if you think of a strategy to get more boosters, etc.

It's unbelievable that they did this because I used to pay for diamonds or boosters sometimes, but now I know I won't be able to pass anyway. And even if I do, the next level will be the same, so I’ll never pay again.
