Hi! I know the theme is horror in general, but I was wondering if it's ok to make a game that gives the feel of horror and suspense (like dark ambient, doors closing and maybe some spooky sounds) but it's not actually scary, there're no jumpscares and monsters. For example, it feels like a horror game and you get scared by the ambient but at the very end something unexpected happend like this was all a halloween party that tried to spook you or so.

Hi! Yes, that’s absolutely fine. Although this is a horror game jam, there is no requirement for games to be specifically scary. Many game submissions we get aren’t horror at all and that’s fine.
