///////////////////////////// TotalCross Breakout ///////////////////////////////////
///////// v1.01 � 2004, January 28th, Johannes Wallroth, Germany////////////////////
/////////////////////////// www.programming.de /////////////////////////////////////

A very simple Breakout clone, made with Frank Diebolt's Game Library for TotalCross.
The game has three levels and different blocks - the yellow ones need 3 hits to break and change
their color from yellow to orange to red - the other ones are destroyed at the first hit.

The game can be played with the stylus and (not very good) also with the keys.

The program works only on the new 320x320 high resolution OS 5 color devices!

Many thanks for TotalCross - http://www.TotalCross.com.br
and the SuperWabaJump Toolkit http://sourceforge.net/project/shownotes.php?release_id=204193
which were used for this program.
