There's a walkthrough on the Mino Hotel Wiki and we will keep updating it as we go, so it's safe to say there will be one for the full game.
That said, the game is designed and balanced in such a way there will never, ever be enough time to do everything. It's mathematically impossible to 100% the game or "play it perfectly". And when I say it's impossible I really mean it, there's absolutely no time in-game to do everything and there never will be, not even if you are a mathematical genius with a spreadsheet. So the walkthrough won't be a guide on 100%'ing it either, it will just give some general guidelines and a handful of specific pointers.
Instead of being a game where you're meant to seek perfection, Minotaur Hotel is about you prioritizing and focusing on what you think is the best, or most important thing. Do you want to hang out with Kota, Luke or Khenbish? Or do you want to help with Asterion's project? Do you want to play archaeologist in the valley or build a gym? Do you want to play detective in the hinterlands or do you want to hang out with Storm?
There's no perfect path. Just be yourself and the game will react to it. And, unless you treat Asterion badly, the game will keep going.
