6Graphics are good, but I'd really like a higher resolution. (Get rid of the useless background effect, if necessary.) Gameplay is good, but lack of sound effects and decent menus lower the overall impression.

8A school project? Amazing work. I wish I had that kind of talent when I was taking C++. Great game, fun, and graphics are what you can expect for a bowling game.

10Nice little game :) Some cool background music would enhance it a bit ;)
