I'm going to be as honest as I possibly can.
It's incredibly remarkable that you were able to produce this in 48 hours. You should be very proud of this.
You should also be very proud of the fact that your game is one of the only ones with an actual story (that I've seen so far). The story execution was great; the graphics, the mood that the music provided, and the feel of the game contributed to the Count's depression. You did an excellent job with that.
I'm going to be a bit nit-picky here. Firstly, the font didn't do a whole lot for me. You chose a very basic font, and I feel that was one area which could have contributed to the story and feel in an even greater way.
Secondly, the Count's starts and stops in movement are abrupt and inhuman-looking. Gradual starts and stops in his walking would give the game just a little more polish.
Additionally, playing on a keyboard, it was a little confusing when the game told me to press X to open. I knew that meant Q, but it would be best if all the tooltips changed depending on whether or not a gamepad is plugged in.
Lastly, the Count's periodic tremors got to be kinda annoying when I'm trying to walk somewhere and suddenly he's collapsed on his knees.
I think you did a great job with this game, and you picked a very unique route to go with this game jam, albeit, your connection to the theme is rather weak.
