At first I was really confused about what to do in the game. There were no instructions, so I basically tried to press every button and click everywhere.
Eventually, I understood that clicking the "!" balloons had the fish interact with it.
I didn't quite catch the "E" mechanic, I also didn't understand what the "!" balloons did.
The fish also went behind the screen when clicking somewhere on the right side of the map.
There were no tasks, dailies, music player, history and tooltip interactions, so I didn't understand what those were for.
The fish was really cute and I kinda liked the aesthetic of the game.
Some small feedback and guiding the player through the game at the beginning could improve the gameplay a lot.
