Pixel games(preferably sidescrollers) that feature ghosts

I really liked Ghost Hunter Vena and the Sprite Hills game in the mansion, would love to play more that feature ghosts or shadow-people as the enemies!

This game https://ulmf.org/threads/uzurazanakku-quail-setariano-setarias-makyou-rj323773.14778/page-2 has a haunted mansion area, with ghosts and spooky enemies. Very good game, but futa protag and quite a few futa on futa scene so be warned.
