Wasn't sure if this was gonna pass through
Graphics: I liked the black and white and they suited the movie, but you need to work on the drawings. Sometimes they were alright and sometimes they were pretty bad. Also, you should decorate the hotel a bit with paintings and such. Anyway, the graphics were decent, but practice a bit on drawing.
Sounds/Music: Some nice wind sounds at the beginning, that suited the movie very well. The footsteps were also nice, the bell sounded a bit weird (wasn't that an MSN sound?). The voice-acting was decent, the voices weren't really that bad, but it was pretty hard to hear sometimes. Luckily you added subtitles. I would've added some music in this if I were you, I think it's very important in a movie like this one. Some scary music would be very nice. Anyway, the sound was one of the best parts in this in my opinion.
Interactivity: Well I know it isn't a game, so it doesn't need that much interactivity, but it would've been better if you added a menuscreen. The movie isn't that long, so a scene-selection isn't really necessary (it's always good if you add it though), but you could add a button to change the quality there. Also a button to view the credits and something with the volume and subtitles. Just some ideas (and don't forget a play button of course).
Overall 5 out of 10, 2 out of 5. I didn't blam it, but I wasn't really sure if this was gonna pass. I thought that if it was gonna pass, it would have a score of like 1.80, but seems like it wasn't even close to getting blammed. Anyway, I saw at the end that maybe it'll become a series. I ain't really that interested in part 2, but I think you should still make a second episode. The most important thing right now is the drawings, improve those and maybe it'll become a pretty good series. We'll see.
