This game is lovely looking. Like a trapper keeper cover combined with myst. But I am stuck, I keep reaching the part of the game where you enter the room with the 4 trees just to get booted out of the game. I tried clicking on them in a order of youngest to newest and that didn't work. I found the green tear drop under a floating rock before that, but that's as far as I can get. Is that the end of the game?
