Lookie here, I'm reviving another old game thread from back in '04 :p
This is pretty much a "proof of concept"
test-run WIP that completes the 1st home in a bit over 5 1/2 minutes. Provided there's no major strategy changes, an optimized effort could certainly get that time down to about 5.
I've got some more detailed insights in the userfile link, but what's notable about this game is that each family member appears to require a minimum number of rooms to be scared out of, until the game lets them completely flee the property. So basically, spending time scaring the daylights out of them in a single room is a time waster. It's faster to just quickly herd them out of the minimum required rooms
(green traps work best here) before chaining together enough traps to make them head for the hills in utter horror.
I've been wanting to look into this one for a while. I think it will turn out to be pretty entertaining once all is said and done!
edit: I appreciate the encode, god of destruction :)
