Interesting game.
Umm... You could include a map of the thing. The rooms were confusing me like going through a window and ending up somewhere on a different level with no windows. And... I found that sometimes, when I dragged something and let go, it stayed in the same place and I have to drag it back or exit the room. You could also make it so that we can exit out where we came in... It was annoying to have to go through the whole thing again just t get out and think of a new solution... Ummm....... Maybe post a walkthrough for those of us going insane trying to figure out what to do next? And... err... your rugs (if thats what they are) are badly drawn. Also your moon looks like its right there between the castle walls. It doesn't look as if it is far away. And your perspective of the pipe in the overview looks funky when it comes out the front of one building but goes back to the building farther away. Yea... and one last thing. You can convey us hints through thoughts our character would have when we click on certain things... Or the light switches. Or you could do the speech bubbles when the character talks to his/herself like in some point and click games. Can't wait to see the finished version.
