forgotten roblox horror game

a year or two ago I remember consistently playing an asymmetrical horror game on roblox. recently the game popped back into my mind and for days now I have not been able to find it on roblox or google because I have forgotten the name. all that I remember is that on of if not the only map was a white mansion with a small basement with a large boating shed and a dock. the only killer/slasher I can remember is a roblox character with a wearing a troll mask and welding a seldge hammer. 1x1 might have been an enemy and I have a faint memory of a swampy green ghost with a mouth like figure from doors. if anyone knows the game or knows something that would help my search that would give me a lot of help. thanks
