I like the concept! The little skeleton guy is just doing their best! I could see this leading to some really interesting puzzles as it goes on.
Have you thought about the narrative framing of the game? It might be neat if the concept and objective were explained by way of saying something like, you've noticed that too many things are dying in the forest, so you're going to see if something has happened to the forest's dryads and caretaker druid.
