Please explain the issue you experienced in the most condensed way possible
During the mid-game and beyond, the performance gradually becomes heavier, eventually slowing down to the point where it hinders the progress of the game.

I've captured a screenshot video of the final game progression speed, so please check the attached file to see how slow it is.

Although the game doesn't crash, the progress becomes incredibly slow, making normal gameplay difficult and forcing me to quit before reaching the final completion.

Many people have reviewed that this issue occurs regardless of computer performance, so I understand it's not just my problem.

I have played several times since the release date and in late March this year, but I haven't been able to confirm that the issue of the game becoming heavier after the mid-game has been resolved.

Is this problem now resolved?

If it is not resolved:

Please let me know if you are aware of the issue or not.
If you are aware of the issue, please tell me when you plan to fix it.

Thank you.

Please explain how to reproduce the issue
Mid to late 1800s

Is there anything else you think could help us identify/replicate the issue?
The attached file is an older version of the saved game data before the game was paused, but when I tried running it just before sending this message, the performance was still heavy. If the bug causing the game to slow down after the mid to late 1800s has been resolved in the current version when creating a new game, please let me know.

I have attached a save game
Yes

Yes of course this is a known issue; this has been the most common complaint since day 1. If you want a deep dive regarding why the game gets slower over time you can read it here. If you want to read about some of the improvements they implemented to make the game run faster, you can scroll down to the performance section here.

Even at this point, it has been confirmed that the game is too slow, making it difficult to clear.
I think there are hardly any people who have been able to clear the game in this state, but what do you think?
The gameplay is fantastic, but are you not going to take responsibility for selling a game that can't be cleared?
In fact, with all the bugs, are we not being made to do paid debugging work for a game that is still in development and has been released?
