Maybe the atmosphere is somewhat missing? I'm a bit of a sucker for spooky h-games if you couldn't tell.
Also I meant taking away the music on player death-cutscene only, fyi
Well I made custom music for the death-hscenes so I don't want to take that away. As for the atmosphere, it sounds like you're looking for a scary h-game which succubus hunt isn't really meant to be unfortunately.
