Sorry for the necro but I never found any walkthrough whatsoever online. That is why I will put it here
First and foremost... please support the devs. They can make great stories and gameplay. They need to be supported...
This is my playthrough with the harem ending (no cheat)
Walkthrough (summary not daily)
This game is a multiple ending game with bad ends mixed in between.
The game itself is simple enough just manage the spirit level not to be zero or over MC own spirit power while lowering the hatred level to 0 % to access the next story part.
Whenever it reached 0 %, a story event will trigger and in the very next day the stamina will be fully recovered all the time.
Resonate will decrease hatred and spirit power
Cleanse will decrease hatred and increase spirit power
Both will increase favorability
Cleanse is kind of a double edge sword, catch all the dark orbs and the hatred will decrease immensely with minimal spirit power gains, if you fail well... she will absorb the dark orbs and increasing the transfer amount of the MC spirit power to her which can cause game over since she becomes a demon
Resonate and Cleanse will go up in level according to her favorability. The higher it goes, the more her heart open to the MC and the more difficult Cleanse will become.
Burn is my ultimate weapon since it can give you and her beneficial passive status gains. Give her gifts! MAXED this one... and reload if the RNG still gives you crap status at higher burn levels.
Work, go outside, spirit training, and rest is self-explanatory.
Park is used to unlock Luna in the end; you do need to have some money in your pocket. Save up!
Just reload before making all the choices. Only one answer is correct most of the time.
Can also exploit these events for stamina recovery items if Luna appears there and sold them in her traveling store.
Work, spirit training, burn, and cleanse all have minigames. Only cleanse cannot be skipped.
Spirit training, just remember ONLY to release your button press whenever you see a white (!) exclamation mark, ignore everything else
Burn, collect the blue orbs, and stop the red ones from burning out or entering the fire (pray to the RNG God)
Work is a timed matching game. Kinda annoying on higher level, just remember that whenever new ghosts show up, new guys with her requirement will spawn. Not very helpful I know, but this is why I bought the amulet from lvl 3
Cleanse is this game equivalent of the boss fight, especially Yuan which can literally damage the MC. Catch the flying orbs and careful not to excess click too much since it seems more orbs will be flying out in the next round if you do. One orb will needs two clicks.
You can actually catch a breather here between rounds if no more orbs flying out before... eh... you pump her with spirits...
Status that you must be aware of is demonization and injured soul.
Demonization will increase the ghost spirit power like crazy. But since I am a cheap guy and keep them all at borderline zero with my MC ever increasing own spirit power, this rarely become a problem. But you can use that spray bottle in desperate times...
Injured soul on the other hand is very annoying since I am forced to cleanse. And each time you cleanse, the MC can be drained A LOT. The coffee can be used in desperate time, but this will cause stamina drop. I prefer the ghost book for this malady.
Both will be gone in time eventually...
The most important thing is... there is NO time limit as far as I know (I used 40 days on Daier and 18 on Yuan)
Now on to the girl
Daier:
The tutorial girl... really... Maxed out work, spirit training, and burn with her. And use her time to unlock Luna too and complete almost all the Park and Cemetery events
Buy amulet on higher level to avoid the mini games
Buy the blue most expensive item and burn it just before Daier finished; to prepare for Yuan (this had doubling effect on spirit power)
Buy lots of hatred reducing, favorability increasing, incense, and some ghost books to burn for Yuan
Finish Daier after you have prepared enough (in my case 1 million spirit power, 100k money and lots of items)
Yuan
The real case... you have to deal with all her events which will locked out many things for few days. Just soldier on, this is not a bug.
Burn her the favorability and hatred items on day one, do this and combine it with resonate. And follow the events.
Bring her hatred down as soon as possible!
Do not deplete or increase her spirit power using items unless you absolutely need to. Her soul is a glass, easily injured or demonized.
If you prepare for her enough. Then you will have no problem soldiering through her events.
At some point if you ran out of ghost book or her soul becomes injured, you will need to play her cleanse game. Well. I say this is Touhou on easy - medium mode... but with your manual clicking chasing the many many many orbs... Good Luck! She attacks you too and will literally drain the MC spirit power every time the pointer hit box got hit... well... you know, standard Touhou game...
I finished Yuan with 100k spirit left from my big 1 million bank. That will give you enough info on how difficult this is for me... And I still failed to get her scene from the temple... dang it...
When you finished her. Congratulations! Pick your ending
Overall, the story is great and funny, the gameplay is unique, voice is on point Chinese which sounds very refreshing in my ears. Don`t pass this up mates..
