I don't like leaving negative feedback, but so far the game is rough. The writing, the maps, the events, the storyline... The storyline was a particularly grating point for me.
You're going for a "the world is your oyster" approach, which is an easy but ambitious choice, but it doesn't mean you can just drop the player off completely aimless and not knowing where to go next. Even in an Isekai setting, there's that one unavoidable NPC who approaches you early on to give you a purpose.
In open-world games, there's always this main path that guides you without railroading you into it. It's here specifically so you can go for the long-term goal if you don't know what else to do, and along the way you'll find plenty of opportunities to go off-track with shorter stories.
You as a dev know the route like the back of your hand, but we the players have no idea. The people in "Starter Town" don't have anything to make you do when you first talk to them. A big miss was the building right in front of the entrance that's unoccupied, even though it's logically the first place a player will look into. You finally get a clue if you keep talking to only two villagers, which is unlikely to happen when they all brush you off in the first conversation you have with them.
I'm absolutely not telling you to quit while you're ahead and I hope you won't, but there's plenty to improve and I hope I'll come across this game again once it's fully baked.
