Very hard to see from this little yet, but I sort of did enjoy about the idea of walking with that ghost around the area, and then being able to get close enough to paintings to click them and see some info.
Also, the amount of info was quite suitable too, since it wasnt a wall of text, but text you can actually read through in seconds, making it not stop the flow of the game. As in, I could see this could work as some good edutainment kind of thing at school class for example for elementary schoolers
As in, add some platformers that you actually have to jump on top of to get to other areas and see some paintings, and suddenly, that painting you get to through some hopping starts to feel like a reward you want to read due to feeling it is a reward.
Especially if adding some other game there at same time, like maybe you need to collect info on 20 paintings, and then you go around and you get that info by clicking on these paintings, at which point they are stored in your inventory and you can click any time to see the same info again (with the picture of the painting included), and maybe there are even some doors which make you some questions about the paintings, as in, doors wont open unless you know what year Mona Lisa was painted and 2 other questions, answers which you can find by clicking the paintings.
This could work, for as I mentioned, I sort of was hoping the one room to be bigger, and there being platforms to jump on top and see one painting there on top and was looking forward to getting on top of that platform to see the painting and the info.
