This game is a lot of fun! The only thing I kinda wanted to see is some horizontal movement to the fruits, so they make an arc which could be more pleasing to look at and even more challenging to shoot at. If you're not sure how to do that, it's quite simple: You can just give the fruit a permanent force of a random value from negative to positive, negative values would go left and positive values would go right, you can apply this force the moment the fruit spawns so it's not applied every frame. But overall great game, super fun!
