Hello...
First, I want to say that "Extremely slow" in my previous post is not a suitable description for the keyboard problem. I try to explain accurately:
1. Played on a Windows XP computer: no keyboard problem.
2. Played on a Windows 7 computer: no keyboard problem.
3. Played on a Windows 11 desktop computer: the keyboard problem happened. (details: PM2023, win32, 1366x768)
4. Played on a Windows 11 laptop computer: the keyboard problem happened. (details:PM2023, win64,1920x1080)
The keyboard problem happened on both Windows 11 computers is: when I pressed a direction key (and held it!), there was a pause or delay(might be less than 0.5 second), and then the character started moving. No pause or delay if I pressed a direction key and then released the key at once. The situation may be similar to typing an essay with MS Word, if you press a letter key(and hold it), there will be a pause or delay. I hope that you will understand my meaning.
