best distance 1024.
looks nice, sounds funny, and its fun to play.
you should add intro text on first screen saying: "Press space to shoot, use arrow keys to change angle".
?do you have to hold the space to fire stronger?
when flight is ending, and his jums are getting shorter and sound quicker, its good, but text with result that pops up over the character is sudden, and those jumping could last longer, and we should see him lie down some time before text appears.
some music might be good, im not sure.
