Pros and cons are down below) Check out my vid (the game is the 2d one there):
Advantages:
1. Very sweet game, it spooked me good, especially the sounds of sniffing!
2. That was original! I've never seen something similar.
Disadvantages:
1. Well, obviously, the game is too short.
2. I would like to see an option to run. For example when that thing is inside you gain the ability to run and if you make it - you live. Or some kind of QTE would also be nice.
Overall: That was super cool! As short as it is - the game gave me decent amount of heeby-geebies, my skin crawled. 5/5
Hope my feedback was useful!
