Hello, hello, high taxes,
Thank you for playing the translated version of Colorless Poems, I'm sorry if you have trouble getting through the game.
The hints on that 4-way forest are just telling that there's a creature behind you that will attack if you stop for too long. But, the rule/hints from the beginning are still stood, that is, you must aim for the highest place/point. So, whenever you move toward the way where your stamina bar decreased, that is the right path. The key of this 4-way is to tip-toeing your way so your stamina bar doesn't get depleted too much. If there is no hint within the game, it just means that hints were already given to you before.
