For originality. The idea was so fresh and original that you wow'd me into giving you a 10 for that alone. However, the animation and controls were also very well executed so consider it a 10.9 ;)
Like you said...
very challenging. This is one of the most original puzzle games I've played in some time. Great work on the graphics and controls. Make some more. Great Job.....vp
I would have liked to be able to just play it straight through, without having to go back to level select and select a level. Also, after you get the correct configuration, for some reason you can click it again and break it! I don't know if that was intended or not, but it is bizarre.
I've added the next level button - it was an oversight on my part there!
The ability to carry on after you've finished is there on purpose, mostly so you can see how things interact after they're complete, particularly for the tutorial levels.
Ad some music and maybe have some noise when you move the stuff
