my game has bugs

[frankbsad]

Hi this is a simple little game I have been working on in my free time. Its a remake of a flash game I like to play, it is far from done though. There are a few bugs I would like to ask about,

 

1) When one players missile hits a wall both players missiles seem to be affected.

 

2) How can I make the players slide against the walls insted of the sticky action I get now. That is when pushing diagonally the players stick to the wall insted of sliding against it.

 

3) Is it possible to fire in more than 8 directions? I would like to add 30 and 60 degree fire angles in as well.

 

4) How could I make the missiles rebound off the walls?
