Intresting puzzles, not that dificult and clever but decent. Quick pace, but a little too much. I'm saying that because it felt a little offhanded, with little attention to details as the graphics were not special, the controls simple, the video scenes too hardly cut in and out of the game. The last room freaked me out, and not in the best way. I expected something to happen but instead there was just a ghost standing there, doing nothing. With my little to none expetience to game developing I would say that you have a lot of basic elements right but you need to learn how to use them alone and in combinations better.
Despite all these, in the end I had fun, thank you!
