The graphics and audio are fine - although I think the background music didn't quite fit the game - but it was a rather boring gameplay-wise. It was easy to lose track of the ball since it went so much faster than the fish, so it ended up being more about avoiding the enemies and hoping they won't hit you and hoping that you manage to relocate the ball and send it the enemies' way. Decreasing the ball's speed would've made it more wieldy and helped with defeating the enemies.
By the way, I spotted a bug: when you exit the settings in the main menu, you get stuck in the menu screen since the menu buttons don't reappear.
