If you want to get better at fishing, and you're really bad at it, here's a simple workaround.

It works like a charm and doesn't affect the game in any way.

In order to use the "Simple Fishing Mod", you have to download it to your device and then install it into the game.

In the game, you will be able to set the difficulty level of every fish to "0". This way, you can guarantee that you will catch anything that you reel in.

The downside is that you will not be able to open treasure chests, should they spawn while you are fishing.
