This reminds me of this game: https://www.kongregate.com/games/PeachTreeOath/fish-legend-fish
Which I absolutely loved, glad to see a new version. But the UI makes this unplayable, you need to set your canvas to “scale with screen size”, otherwise it’s tiny on larger screens. 
I am waiting for an update, looking forward to playing it!
