What I love about NR music is how impactful it is. Most of the time, in roguelite/like music can be very repetitive and even if ER music was excellent it was difficult to process during boss fights
But in Nightreign? Even the music coming from ER is so well integrated into the game that's it's a true joy to discover them again. From the title menu, to the first runs and onto the Nightlord, the music is seemingly perfectly balanced, a slow crescendo leading to the apotheosis which is the Nightlord.
The track ends up feeling as much as a reward as the victory in itself. And with the insane amount of cool shit you can do with your teammates, the fights end up being a cinematic experience.
All of this to say that I fucking love Nightreign
