The game looks beautiful and provides some precious minutes of fun.
Very few minutes, by the way, but I understand that for it's a concept.
What I liked the most is that even though the game is short and there's no story at all, I found myself immersed in that situation. The crawling dying people helped a lot, I must say.
The controls could be a lot better. If I made a choice by the begining of the game, the controls should support that choice. I mean there should be two action buttons, one to bite humans and the other to bite blobs. There's no sense in making a choice if you're unable to stand to it because the game mechanics won't let you.
Ultimately, I'd say the game achieved its objective in terms of mood and game feel.
