It's a very long Visual Novel. But each route give us more to learn about the intrigue. It's basically two VN worth of content.
Sometimes, navigating the save file menu, the game randomly crash. Hopefully it can crash right acter saving. Loading will resume right where it crashed.
The intro and end videos could be played normally with this version of Proton GE.
The game is very engaging emotionally. This can give some fight an elevated interest. The fact that it is very long serves to broaden the scope oc the game. The last route is really worth it.

Using GE-Proton9-10, you can play videos normally, which solves the video scaling problem in non-full screen mode in previous Proton versions. Now you can get the best experience by just switching the Proton version.

Videos can be played with GE-Proton9-10, and the scaling issue of videos in non-full screen mode in previous versions of Proton has been resolved.

lavfilters and devenum
stretched full screen cannot run, while whether fullscreen or windowed mode is ok based on unknown reason
crash when start or load after installing unofficial patch 1.01. lavfilters cannot be correctly installed through proton tricks because of dll. registering problems
Op&ed videos can just be played with sound. Installing lavfilters and devenum don't solve the problem, and there are risks that if you skip the videos at the beginning, it quit forcefully. Should wait a second to avoid it. Version 1.01 unofficial patch cause the game to crash when entering play panel in the chinese setting. You need to delete 'update 5' in the patch and keep others. It's possible that only chinese users have the problem because 'update 5' will automatically switch the language to english, thus the game system crash, I guess.

Change to Fullscreen
windowed mode has graphics errors.
Crash when switching to windowed mode.
Opening Movie is not fully displayed when using window mode and stretched full screen mode and needs to be set to Fullscreen Mode.
Summary: Using GE-Proton8-27 and setting full-screen mode, you can play Opening & Ending normally without installing any other components.

I have installed patches for this game, no problem with the patches in any version of protonge and proton. for latest version of proton or proton-ge(which is 7.0-4 and ge-42 on 2022/12/5), install lavfilter videos will play but the playback speed is 2x . audio seems to be fine. Performance overlay shows that Vulkan 60 FPS during opening video playing. Anything else seems to work fine For proton 5 -10 , install lavfilter and devenum, both video and audio works perfectly. Performance overlay shows that DVXK 30 FPS which is the correct playback frame rate. After 70h of game I can confirm that proton5-10 runs the game perfectly without any issue

Install devenum and lavfilters
Crackling Audio Periodically
This game tends to temporarily knock out wifi so you have to exit the game and reestablish wifi for cloud saving typically. In-game saving is fine.
Tried several different versions of Proton and the videos won't play, but everything else runs well. I suspect using the PC methods the videos might work. This is only about four hours into the game.
Videos don't work by default, game crashes the first time the intro video and ending video play, but should skip videos and work fine after the first crash.

As of the most recent proton, installing lavfilters will play the opening's music only, while installing lavfilters in older proton versions will play the op but without sound. Adding devenum and quartz hasn't helped in my case. openings, endings and videos aside, game works fine.
To make the game work smoothly, with all videos included, I did the following:
- Installed LAVFilters 0.74.1 (in the corresponding game prefix of course)
- Installed devenum through Winetricks
Opening and ending movies do not play. Tested with unofficial fan patch.
The vast majority of the game works fine but again videos are completely absent
No Videos at all
Videos are encoded in MPEG1 format so installing LAVFilters and Quartz to the Proton Wine Prefix using WineTricks should get the videos working.

Played through chapter 1. Nearly flawless, except the opening movie after chapter 1 is skipped.
The opening movie after chapter 1 does not play. It is skipped entirely.
