Hey everbody im at a part in the game where i need some kind of seed to grow out some branches for new pathways and somehow i messed up. Does this game have dead ends ? do i need to restart and follow through somthing? Im asking here because i think i messed up the part in the snow mountain stage where that guy wants oil i think? i came back down and he was just a tree. hella made me mad.

No, but there are missable sidequests, like the tree's.
