WANDERING MERCHANTS!
No, not the scammers from Minecraft that call themselves "wandering merchants;" everyone knows villagers scam people. These guys are NPCs spawning at night for the purpose of selling things blocked off by closed shops. While I don't want them to outshine shops, there still needs to be a way to make them useful. As such, I'm thinking that wandering merchants would have this: 20 items. This should allow room for 4 helmets, 4 armors, 4 pairs of legwear, 4 pairs of shoes, and 4 weapons. All twenty items would be randomized, switching around every 24 hours; however, they would all come from a select store (ex. Brip's).
This should allow the game to retain its more Animal Crossing-esque mechanics while providing players workarounds that made Animal Crossing's shop closure mechanic work out well on their end. And yes, I know my inspirations.
That aside, here's a set of phones:

They're rotary phones because those are cool. Having watched a lotta old cartoons when I was a kid, like Tom and Jerry and all that, I know that you have to push the turntable around to dial a phone with those things. I wouldn't exactly imagine Eliatopians having cell phones or knowing what they are, so there's that.
Also, here's a species of Grunt I've designed for the sake of giving people a reason for Ice Runes to exist: the Yeti.:

So yeah, there's that.
