Hi there and Happy Halloween! I played your demo among others for a big compilation video for the occasion (You can find the time code in the video description).
I love the idea of being chased by a Plague Doctor, considering how many questions it raises in the player. If anything, I just found the demo to be a bit too short! I would have loved to see a slightly longer, more complete scenario to drop a hint or two to the nature of the game rather than just geting caught, but the mood and the setting is top notch. Good work! I'd love to see where this leads.
