Great feedback! We'll definitely make sure to be more explicit in our level layout and design to help guide the player towards a more natural understanding of the grapple mechanic and clean up some of the initial platforms in the forest area!
The lantern mechanic is intentionally set to drop when you grapple to set up a more nuanced decision by the player of when they need to leave the safety of the lantern to reach a switch or puzzle, but I agree our presentation of that choice was left a bit unclear, we will also work to make that more explicit in future iterations!
Thanks for taking the time to play and we hope you enjoyed the current release!
