omg, thank you so much, I got lost looking for the path, so your advise on going to upperside (even if it wasn't that specific) helped me have a good look at the signs for the path to upperside, thank you!
How do I progress the game forward? I've been stuck in the same (6?) spots for almost 5 hours. I've done what seems like all the side quests, and I've beaten 2 bosses (octopuss mom, and glowing mutant). How do I move on to the rest of the game?
