TODO

- Check speed of algorithms, use gprof for that
  Read http://linuxgazette.net/100/vinayak.html for more info!

- When you lose on campaign mode, you must be able to CONTINUE (10...9...8...etc)

- Add extra ball prize (++lives)

- Add training, easy, medium, hard levels 
  (change speed/friction of ball, in training score must be always zero, 
  and the player will have a 'hand brake')
   
- Add levels

- Campaign mode [ ALMOST DONE - LACKS HI SCORE TABLE ]

- Add tile palette to map editor, for easy selection

- More tiles, like arrows, walls, etc

- Bounce of ball against corner walls is wrong, must be improved!

- Add alpha transparency to tiles (so we can make glass, etc)

- Rotation of the ball is not accurate (sometimes it rotates backwards)
  This problem is called 'gimbal lock' <-- SOLUCION AL PROBLEMA: GOOGLE!

- Add a console to modify/see vars on the fly

- Installer for Windows, (for Linux too?, check Loki installer...)

- It compiles at random under Linux, sometimes it works, sometimes not. (WTF??)

- Add more gameplay (power ups and other arcade-like stuff)

- Test Map button for Map Editor
