Really good game with very good story...

The only thing is that I did get stuck at one level (the second with the purple blocks) and there was no way I could see that I could restart the level, so you should do a menu option for this case...

This was something else ... I found the concept very interesting.  The graphics and music did a good job in setting the atmosphere.  

The puzzles were challenging. I solved 5 or 6.  But the most interesting feature was how the goal of the puzzles and the longing of the player seem to be connected.

Good job!
