Hey, glad you liked the concept! The cursed (the one with the shirt that destroys the bushes and trees) should normally be able to walk through the destroyed obstacles. You can try this in the menu before the game actually starts (c.f. video: https://drive.proton.me/urls/7VNX9BCW70#smSFx9R3ZxVN ).
You say you cannot reproduce what happens in the linked video am I right? Thanks for your feedback!
