This is quite good. One thing that was not clear to me until I was at the end of the first chapter was how memories worked. It seemed strange that I needed to be in the first room to form a memory of the picture even though I had it in my inventory and could have in theory looked at it from there. If the rule is that you cannot make memories from things in your inventory, I think you could signal this by auto toggling to the objects in the room tab whenever the REMEMBER action is selected.
Overall, I enjoyed the game.
