Well I can easily say this was a very well made, fun game, but there was one major problems. It's been done about a thousand times. When you try to make a game as generic as this, that you know has been done multiple times on multiple sites, you have to do SOMETHING to make your version stand out. You failed to do that.
You had one mode, arcade mode. As if that was generic enough, I start playing it only to realise there is no level system. When there is no level system and only one mode to play, you begin to wonder what the point of even playing the game is. I say the most important change that would need to be made is the addition of a level system. Just something simple like you stay alive for a minute then you go to the next stage. And instead of choosing difficulties, just make it one difficulty and have the speed go up as you go through levels. Possibly add more colors at ascending levels.
Another change that drastically needs to be made for this game to be succesfull is more modes. Try doing the usual stuff, marathon mode where you can just keep playing as long as you want, speed mode where maybe you only have 5 seconds to aim before the ball shoots, simple stuff like that in addition to the arcade mode I previously suggested.
If you just add those two things I think this game would be able to compare to the thousands of other games that are almost identical to it. Anways despite its lack of originality and diversity I'm still voting a 4 for its quality.
