Great job on the visuals and bitter-sweet story.

Absolutely loved the style

The story behind the game was bitter, yet amazing.

I hope to see a possible chapter 4 in the future.

That was good! The visuals have quite a lot of potential, and the audio works really really well. 

I really enjoy the implementation of folklore in the game, it was super cool to see something old school get in! I also like the interactions that were in the game, and the storys progression was pretty good!

Some feedback:
The walking got repetitive quite quickly. The games that are heavy on just walking around that I've really enjoyed playing usually have smaller levels with quite slow walking speeds. Making things smaller makes it easier to polish it and make it feel really good (that applies to everything in games really, vlambeer came up with a neat rule called 4:44. can be worth checking out). 

Otherwise it was a bit difficult to figure out what to interact with. I got to the last bit when you are supposed to click her, and I just walked around for a minute or two, until I started randomly clicking on the screen and accidentally clicked her. A large outline that reacts when you hover it is a very clear way to show what can be interacted with. Doesn't work with all games, but it's there.

All that said, massive congrats on submitting to the jam! That in itself is very impressive, and you did a very good job making it all the way. 

The sound scape was nice, it had the mood and feel of a good horror in the woods. Accompanied with the simple silhouette style visuals it was nice. Also the fitting setting/story, really fun. Short experience but nice :D Maybe a personal bias but I'd love to see more of the interactable, maybe to give more of a slow burn feeling, but like said, that's personal preference. Btw, no idea if picking up the key did anything, heh, I assume it did but I just missed it xD

Nevertheless, good work! ^^

Nice story! Made me think on other kinds of relationships in such scary scene like son/daughter, mother/father or brother/sister and who they lost

I liked the asthetics, the running sometimes seems to be a little long, thats an issue we had too in our game, its really hard to balance that.

Very atmospherical! Loved it. Talking animals are the best. 
First "boss" felt a little bit out of place tho being blatantly "evil and agressive" in this silent melancholic realm of Plague
Overall, nice job!
