I really liked this one! At day three, I struggled with water but realized that I don't have to collect bottles. (What a revelation. :D) But I made it through! I also liked that you can collect the sticks and pretty shells but cannot do anything with it. It makes you feel the cluelessness of this character, or as if you could "rate" with that how well you have done.
The only thing that confused me was that there are fruits etc. you cannot reach. It did not feel right for me, for example, that you cannot go on to the green grass.
Anyways, a nice entry! I really enjoyed it :)
