There was another math adventure game I played on DS called Make 10. It was fun for months and encouraged quick thinking, but almost all the characters looked the same. It would be great if more games had unique characters like this!

I spent so many hours playing THPS 4 and now I just casually listen to this song from the soundtrack. 😆

Really? That is some serious stuff and I hope you are recovering okay. How bad was the damage?

yt-dlp can download most videos, even if they are restricted on normal YT. A premium account might help.
If you need to use an account for some reason, there are some flags like -username and -password in the documentation but I've never tried them.
