I can't lie: what started out as a relaxing walking sim with oddly out-of-place trees turned into a one-river rage game for me. I never made it across the logs, unfortunately, and I wish I had. This was a surprising entry for me, since I played it one time through, quit, saw the comments, and went back for the branching paths. Quite well done. Other than the platforming being old-school-pc-game hard on the third river, I had a really good time getting as far as I got.
Love the tune in the first area, though as others have said that area could have either been muuuuch shorter (just the info pillars, a quick 10-20 meter walk to teach the player how to make the goat follow, then the forest entrance) or left out entirely. I got my goat eaten once in the forest and remembered what I'd read the second time through it; that was a clever way of telling me what to do.
Overall a good entry, suffering only from the river platforming and pacing at the beginning of each route. Well done, thanks for giving us a game to play!
