I would say this was unexpectedly good considering I went in blind without anyone recommending me this manga. If you may you can describe is as cute artstyle manga which sometimes gets horrifying and dark.
So basically this manga follows a similar premise as Sword Art Online, stuck in game and all that but this shows a different light of how people react and behave differently, some accept, some don't, some try, some don't, some enjoy, some don't. But even this isn't the main plot at all as this manga dives deep into the world around and the "bugs" these debuggers are stuck finding to ensure a safe way back home.
Very interesting manga with a lot of game-development related terminology. A fresh take on the isekai genre you can say.
