I got to the end of the game and it said I hadn't discovered anything, but I'm really not sure what I'm supposed to do. Nothing in the inventory combines and there doesn't appear to be any way to use inventory items outside of the inventory. If there are additional controls a mention of it in the description would be helpful. I played through twice and nothing changed. Left the safe area multiple times, examined the water pool multiple times, still no way to combine items and no other items to pick up, no way to use items outside of the inventory, ect. If there is something else to do here or some other way to do it it really is not obvious.
Playing the browser version btw. Also, I want to make it clear that I left the safe area and examined the pool several times inbetween each rest. The only thing that ever changed was the body disappeared and I was never prompted with any way to use any of the items I had in the inventory (which after resting was only the water bottle and the tablet). I tried clicking literally everything several times each and nothing happened. Like, I'm just really trying to make it clear that I did absolutely everything that would have been obvious to do. I've played a lot of adventure games over the years, I'm not new to the genre, I understand how they work, so I'm really trying to make it clear here that something is amiss beyond basic user-error.
