The only action required is to put the aim at fish, you don't need to press other buttons
I was playing again and I saw that it was really difficult and frustrating
The game consist in 2 mini games
The fishing: Needs to put the aim at the fish till it reach the top of the screen
The purifying: Move the aim to the vortex and repeat till complete the mini game
The fish come corrupted in a way that its can depletes the energy and endurance, this mini game reduces the corruption
Sorry, the only way to exit the mini game is completing it
