Approval of God: SWERY loves fan content of the game, so much so that making games "fan-friendly" is apparently a core tenet of his game design philosophy. According to him, the best works are the ones that continue to impact the player long after they've stopped playing, and making characters easy to draw/write about/cosplay allows the player to keep interacting with, and experiencing, the game world long after they've stopped playing.
Doing It for the Art: Despite the dated looking graphics and animations and lack of polish, the game's developers still managed to work in quite a few details not often seen in games with much higher budgets.
All the NPCs have fully rendered daily life schedules and are fully animated entering/leaving their cars, buildings, or doing other activities.
Characters sleep under properly animated bedsheets.
Flip-Flop of God: Are the "Other World" encounters actually happening, or are they just in York's head (and Emily's)? Not surprisingly, SWERY's been asked this question in multiple interviews... and he's answered in the affirmative to both possibilities. Taking all the interviews into account, the answer seems to be something along the lines of, "The shadows represent malevolent spirits, so their encounters are mostly mental, but because mental states can have a physical effect on people, they can be fought off in a physical sense and can have a physical effect on people by affecting their state of mind." Or something like that.
Troubled Production: Many, many websites noted the game's resemblance to Twin Peaks, and the developers noticed this, so they redesigned the characters and rerecorded lines, mostly for the prototype York, David Young Henning.
York's original name was David Young Henning (which would be recycled as a Mythology Gag in this game's Spiritual Successor, D4) and he also bore more than a passing resemblance to Dale Cooper, the Red Room actually did look more like a "Red Room" with the twin angels being Expies of The Man From Another Place, George had a slightly more elderly appearance with less facial hair, and the song "Miss Stiletto Heels" may not have existed in the original version, with the song "Pillow Stain" in its place, which can easily be found in the game in the sound test. The title was also originally "Rainy Woods". The Trailer can be seen here.
George's old design was still retained in Deadly Premonition as the model for Richard Dunn, owner of the SWERY 65 bar and father of Quint Dunn.
The ability to hide in dumpsters suggests you were to hide from the enemies, rather than fight most of them head on. You can see this in most of the Raincoat Killer segments. Which possibly links up the fact that the combat aspect of the game wasn't originally present and was added early in development to keep the publishers happy. Maybe the game would have been more stealth orientated.
