A solid Realm in my book. However still some flaws:
The popups start waaaaaay too early on that jump,please let players land.
More popups blind you.
Some parts of the track go up a bit fast, launching the car off the track, requiring either knowledge about those areas or grip-flying.
I would add some more particles for flair
good job

And those darn laggy extremely bright ruining your day walls. >:( This realm has some really cheap hazards just saying

The looks of this track is beautiful, it's one of my favorite looking realms now. To a cool looking city to burning blazes of giant furnaces. Gameplay wise it's pretty fun, but I feel like the biggest flaw are mostly there's very few checkpoints and I get frustrated dying on some of the simpliest parts.

I think there just needs to be more checkpoints.

just played the updated version, i really love the changes made to it!!!

Personally i would change the color of the sky, or add clouds to it, another thing i found unfair is the fact that is very difficult to see what parts of the fire kills you (maybe it was because i play at almost max bloom brightness idk).

Things i would personally add to the realm to make it look less empty:
-More glassy buildings
-destroyed glass buldings with various angles close to the player's car, (some like an obstacle to dodge)
-A lot of glass fragments floating in the sky to make it look more beautiful and less empty (and with reflections to make it look more impressive) (i would personally love to see this implemented)
-more obstacles on the first half (the blue-grey) tracks

Hope you found it useful!
