Need some ideas!

So this is what I have so far!

All of the players are related some how, some are brother and sister, some cousins etc. ( it’ll be a group of 6) but the whole family doesn’t talk to each other. Their very wealthy aunt who kept in contact with all of them, just died. At the funeral they are pulled aside and told that the aunt has left her estate to all of them, to share.

Now when they get there, of course there are tons of valuables, but the estate is haunted and they have to break the curse to leave the estate grounds.

I need some fun puzzle ideas, and things to keep it interesting and not just fighting some ghosts.

But I also need an idea for the overall curse. Like should I do beauty and the beast style but have a room with 6 roses in vases ( one for each player) and as the time goes by, petals fall off and if that players rose loses its petals, they’re stuck there forever?

I have a tendency to always go too crazy with my stories and I don’t want this to be too complicated for 2 new players but I also don’t want it to be boring.

Any ideas or critiques are welcome!
