After messing around for a bit, I managed to get it into a somewhat playable state, but it can be annoying to play. Bugs are still there though and I am no PC wiz of any kind and I am currently the November 9, 2021 build of Windows 10. Keep in mind that not everything will be smooth and some scenes will still partially freeze or completely freeze from time to time depending on the animation that loads. I'm probably talking out of my ass for this specific thing, but I suspect the game may have different types of video renders for the webm files that play, be it clothes ripping or during any sex scenes, and just may not know how to handle those when it loads? I've no idea how RPGM works or how the dev made this. If you somehow don't mind being annoyed by the constant settings tinkering and actually want to play it, then maybe you can try what I did. Otherwise, just do the save file edit thing mentioned on Page 5 of this game's thread and watch the CGs.
- I right-clicked the game exe file, clicked properties, and set it to run in compatibility mode for Windows 7 (had to tick this every time the game froze and restarted).
- Ticked the "Reduced Color Mode" box and frequently switched between using 8-bit or 16-bit colors (somehow worked when some scenes would freeze, but switching the color mode made it load fine the next time).
- Ticked the "Disable fullscreen optimizations" option (may not actually be needed? not sure but it's what I did)
- Downloaded and installed the Locale Emulator (by xupefei) and ran the game exe with Japanese locale. You can grab it from a github page.
Some notes on my playthrough that you should keep in mind if you play this game using my methods:
- I always saved right before a potential encounter, be it an NPC you can seduce/sex or a monster girl. Again, the game just loves to bug out during sex scenes or clothes ripping scenes. Switching between the 8-bit or 16-bit color profiles here made it possible for me to advance several sections.
- Sometimes the previous trick wouldn't work on some monster girl battle scenes, especially in a double encounter. In that case, I would avoid a specific monster girl encounter.
- Sometimes in a double encounter, I would use an AoE attack to try and potentially rip the clothes of both monster girls at the same time. That way if 1 animation froze, I would click once or twice to let the game continue and the next clothes rip animation would load, which would undo the freeze.
- When you reach the point where you obtain the maid outfit, do not switch off from wearing it. You will not be able to wear it again despite it being in your inventory. One of the only gameplay bugs I actually encountered, aside from the obvious scene loading bugs.
I actually managed to complete a full game playthrough like this with an in-game time of 7 or 8 hours I think? If you actually want to subject yourself to this kind of playthrough, I wish you the best and I hope that my methods actually work for you. I cannot help you beyond that.
