Wow! Thank you all so much! Never did I expect to receive 6 pages worth of help!
Right I'll try to answer this in order...
Lurrdoc - The theremin seems like a popular item, and the idea of blocking it in so the player can't turn it off sounds brilliant! The uncomfortable environment you speak of will only be heightened by the lack of control animal crossing otherwise offers.
Mixxi - Hospital furniture will appear in the third house as part of the story, and mannequins will also play a part!
Touko - Multiple theories is something to consider, although I don't want it to be too vague so the player isn't sure of what the story actually
is.
JezDayy - The one bridge is certainly interesting, although my town layout would mean the player has to go back on themselves. I think it would flow better should there be another bridge.
Corduroy - Blimey! Thank you so much! The tourist idea is brilliant - I'm definitely going to do that! Perhaps a PWP of those 'face in the hole' boards with a palm tree design at the start could add to this? The first house will be 'overly' normal, so a lounge, bedroom, kitchen, bathroom - but I've then got 2 rooms spare which I could potentially use. I want to use all of the town, but I've just got to think how to do that!
jakeypride - Thank you for the links! The doll remark made me laugh. Perhaps the dolls can fortify the theremin mentioned previously? Haha, all joking aside, dolls won't be making a frequent appearance (although whenever I see them I do get flashbacks of other horror villages).
ForestRabbit - That's a very interesting idea. I love art and making patterns, so perhaps some rooms in the later houses could use my own designs to evoke certain feelings in the player.
beebs - I also admire the small details, and think the main challenge will be the landscaping and PWP's that need to be meticulously placed.
Thank you once again to all those who have contributed so far!
