Hey! I just played your game and I have the following thoughts to share:
1. I love that you went with a touching story approach to the theme. And the way the items were re-incorporated after reaching the summit to further stretch the narrative was a nice touch. Great nuance to the narrative design.
2. When I first started out after the initial dialogue, I was confused what the things on the ground were, and even after realizing they were items I didn't understand the role they played. I tried to collect everything just because I could, but then I started discarding things on accident and it wasn't until almost the end that the intended narrative role the items are meant to play clicked in my mind.
3. The ending is abrupt after reaching the base of the slope. I was hoping for a final sentimental moment, or a resolution that indicated where the protagonist was headed emotionally, so the cut to the main menu was a little jarring.
