It's easy to see how you can get frustrated with this game. You don't have much mobility. That was of course the point and it at least makes for a fairly surreal game. I appreciate all the details put into everything. It may not be that descriptive, but it has enough. I guess the protagonist was supposed to be an Easter Island head. I wish I had some idea what any of this meant.
It certainly takes patience to finish the game. I'm glad you didn't mean 150 years in real time. Of course, I should have realized that sooner. The music is very soothing. I'm stuck at the part with the three trees where you can only climb the one in the middle.
