This was a really fun escape room, nice job :) Had no idea you could do something like that in RPG Maker, very neat. The story was pretty sweet and I was impressed with the character development you were able to fit into such a short play through; I felt very invested in re-uniting the group of friends. The escape puzzles felt logical and satisfying to solve, it always felt like the intended solution was a fair one and there were enough hints in the dialogue and item descriptions to help the player along.
One very minor nitpick is that the staff could only be used when standing directly in front of the wardrobe and not when on the side of it, even though you would get the prompt about reaching the high up bag from both tiles. Another minor thing was that I think you should remove the pillow prompt as it took me a while to search under the bed for the staff, thinking I had already looked there when I clicked the pillow tile. It might be less confusing to have both tiles give the player the staff. But these are very minor suggestions that didn't impact my overall enjoyment.
I think you did a great job with the writing, it never felt forced or like it overstayed its welcome. Each line and item description either helped develop the story, helped solve one of the puzzles, or was funny. No words were wasted, so kudos for that! I had a great time playing your game and the story went perfectly with the gameplay, awesome entry!!
