@SergioCornaga thank you for the feedback. do you think I can mend it with some simple hints? Like:
Making the guy at the top of the climb suggest that you follow the path of the ants, and making the path more visible.
changing terrain and placement of the doublejump powerup so that the house by the one-way path is surely visited when the double jump is collected.
Maybe add a creature at the house with a dialog to really point out that there should be something on the other side
