After seeing your website I'm surprised about the high quality of your game.

Still, one thing is bothering me:

Is this because you wanted it that way or an unwanted side effect?

.. the depot is updated on an irregular basis. Just wait, it usually takes from 2 weeks to 5 months to get your game there.

I can't see your screenshot.

The game froze after I died a lot on level 5.

Also, you should change the ball physics. It seems as though (and it probably does) the ball follows the same path every time for every level.

The interesting thing is that the ball is so hard to dodge, even if it's 100% predictable (only 45 degree bounces, always the same start position).
I needed several tries to reach the second level.

I found that the first four levels can easily be beaten by using the same exact same strategy (go to the outside and then travel around the edge until you win). But I haven't beaten the fifth level yet.

I just wanted to point out:

Can easily be written as:

char filename[10];
sprintf(filename, "L%d.bmp", level + 1);
L[level] = load_bitmap(filename, NULL);

And likewise:

destroy_bitmap(L[0]);
destroy_bitmap(L[1]);
destroy_bitmap(L[2]);
destroy_bitmap(L[3]);
destroy_bitmap(L[4]);
destroy_bitmap(L[5]);
destroy_bitmap(L[6]);
destroy_bitmap(L[7]);
destroy_bitmap(L[8]);
destroy_bitmap(L[9]);

can be:

for (int i = 0; i<10; ++i)
  destroy_bitmap(L<i>);

Edit: Now that you've attached the file and I see you're using C++, the string manipulation is even easier. (Read up on std::string.)

I thought you were exaggerating until I looked.

Hey, finally I've found someone who writes code I can understand! Now if he learned something about designing graphics. I may suck at art, but I know better than to make something that looks like that website. Please, for the sake of all that is good and for all the people in the world who aren't blind, change that website. It hurts my eyes! I like the game, though.
