Thanks! Yeah gameplay wise more was planned. But due to time restrictions.
Like vacuum up dust to properly clean the house, have items which if you vacuum them disable it for some time, due to the vacuum being clogged.
The problem when the ghosts are an actual enemy is that you cannot vacuum onto them and use them as moveable platforms. So we would need a non-standard enemy approach here, where the items you shouldn't vacuum come together.
Also we planned with different sizes of ghosts - so maybe a bigger ghost is not fully vacuumable and damages you if you stay too long.
But Jam is over :D Glad you enjoyed it. Maybe we'll come back to the game later again - but we have active in-development projects running in both teams so that is very unlikely for the near future.
