legally obligated to shout out Touhou which has some banger themes for its forest stages!
Touhou 8 holds "Retribution for the Eternal Night ~ Imperishable Night", an intense chase through an endless bamboo forest, & Touhou 10 has several but I wanna shout "The Road of the Misfortune God ~ Dark Road" and "The Gensokyo the Gods Loved" the latter especially being an iconic one as you take a melancholic trek up a mountainside river.

cool list !
