Not gonna spoil anything but I will say that, having read way ahead in the web novel, this series is something great. I'm enjoying it just as much as I did reading Solo Leveling. The source material is really long too so it's really filling my shounen crave. Game theme, survival games, higher beings, unexpectedly emotional stuff, it has it all.
If I had to give an early rating only 33% of the way through the web novel, purely in terms of enjoyment level, it's like a 9/10. This adaptation is doing it justice too.
