I liked the visuals. So puzzles were quite good, for example sooting few blobs from you, to be smaller. But I was quite confused in the start, when I collect blobs out of a box, the box looked still full.
But once again the art style was really nice. Only thing that I would change is color of the background from grey to maybe more green grey, so it doesn't look too "default".
Edit: But I get, that it is just 48 hour game and this are really small things, so it is ok.
