lmarbles (2D puzzle game)

LMarbles is an Atomix clone with a slight change in concept. Instead of
assembling molecules you create figures out of marbles. Nevertheless,
the basic game play is the same: If a marble starts to move it will not
stop until it hits a wall or another marble. To make it more interesting
there are obstacles like one-way streets, crumbling walls and portals.

As Marbles is meant as a puzzle game you play against a move limit and
not a time limit. This way you have as much time as you need to think.
