The game is functional, but it has a few flaws.
The lack of sound makes it pretty boring overall, making hitting the fish not very satisfying. The whole look of the game is pretty dull in my opinion, with very little detail overall. I also found out that if you hold down spacebar when the character touches the ground, the attack animation won't stop. I also don't really understand what's the point of having a skill-based fishing system if you can just slow down the arrow with W/S whenever you want.
Still, the gameplay is functional, so it's actually playable.
