Nice update! I see more signs around and they should help teaching the mechanics. When designing my any% speedrun route I noticed something kinda odd about the gem placements:
As gems are the main collectable and scattered along the main path, these 9 gems being hidden in the cave with the trophy felt bit weird to me. I think maybe it's better to move them to the main route (and leave only the trophy here) so it's easier to unlock the final area (Lost Isle) :3
