OK so, it's possible you ran into a bug that prevents the game from progressing. The version uploaded here is outdated and lets you take a bus to the city early, which breaks the trigger that tells you what to do and locks you at sunset. You can try reloading a previous save and talking to all 3 neighbors in town, and then the game will progress as intended.
That aside, it won't give you a lot more direction, since it's supposed to be more of a sandbox/simulation game with routes you progress in whenever you want. Right now there are 2 scenes for each of the 3 characters (prologue aside), which is only enough to get halfway through the 2nd day. So if you're not stuck at sunset, then you probably already did all the content current in the game. Maybe I should add a tracker to how many scenes you've run into that gives you a message whenever you've seen all of the released content.
I'm adding exclamation marks where necessary, but as you said, the map is small and you'll know how to progress 99% of the time by just looking around and running into the main NPCs (and sometimes seeing secret scenes, tho there's only 1 in the game as of now).
I hope that helps! You seem to like the premise of the game so feel free to stick around in the future.
