Welp since there aren't any reviews for this manga yet, I'll go ahead and give my quick thoughts.
I scored it pretty high because I enjoyed this manga a lot more than I expected. It started out pretty okay, but really grabbed me when things turned dark in the first chapter. The more I read, the more I wanted to learn about the game itself and the characters. I looked forward to seeing what kind of game there'll be.
It's too bad the manga is so short. It made some parts feel rushed, or we didn't get enough out of it. It would've been so much
better if it had a few more chapters and took its time. As much as I enjoyed the main two guys, I wanted to learn more about the others, but the manga never really delved deep into them. Especially the female character that shows up, but is barely around. More like we barely learn anything about her. We don't even see her around the ending...
Overall, I found this manga a lot of fun and enjoyed the characters despite how short it was and rushed some parts were.
