Thank you very much for your comments and critics. It really helps to get a goal and even to make this game better.
I'm pretty sure there are lack of contents that could make this better, i really love that idea about the buildings and then inside the building, the doors, seems pretty interesting.
The fact that some clues will be on the maze to solve the door quest, should make it better improved, but i hardly had time to finish it.
I will consider every one of the points you have kindly observed for this or for another version of this and even for next projects, again, thank you for playing and for commenting!
