Simple concept, decent game.
I enjoyed this game because the instructions were easy to follow and it had smooth controls. The purpose of the game is simple so I got into it quicky. I thought you picked some good music to incude in the game as well. The artificial intelligence was a good challenge by adding an enemy after every point you collect.
I've played several games like this before, so I'm somewhat used to these games. I thought the game was amusing when losing one, but it doesn't seem like a game you would want to play multiple times. Nothing really changes, you'd have the same experience over and over.
Overall, I liked the game. Like I said, the replay value is very low, but the simplicity of the game is what makes it great. I'll be on the lookout for more of you games, keep up the great work!
