Javascript inkball

Inkball is a video game developed by Microsoft.
In the game, you try to direct balls into holes of corresponding colors by drawing lines which the balls bounce off.
This game is inkball written in JavaScript. Play it Here!

The ball animation is actually smoother than what it shows because the gif's frame rate is low

Status

ball bouncing:
- bounces in correct direction off of walls
- balls bounce off of each other in correct angle (works VERY WELL)
- bounces in WRONG direction when it hits lines
  - In release, i'm using a direction changing algorithm, which does not reflect based on the angle of the line
  - I'm trying various algorithms to calculate the ball's direction using the lines direction and the ball's direction
  - sometimes the ball doesn't make the line disappear and does not change direction at all.
getting into hole
- says you win when ball goes into correct hole.
- tells when ball gets in wrong hole.

fyi i'm using the processing editor for this project
