I made a request for this game to have an entry on steam grid DB, a website where peeps make and upload images to be used with non-steam games when used trough steam. i made some super basic ones using the mansion artwork at the start of the game + the title screen, you can find them here: https://www.steamgriddb.com/game/5523955
And here is how they look on steam :>
EDIT: in The versions i uploaded, i removed the 2.0 since i know the game will be updated in the future
