man i really like your maps, your pack has a vast majority of themes and a good difficult curve. always inclined to play in one of your maps in netgames. As of the recent update i have few thigns to point minor stuff
Emerald Coast -
The first cut with a turn to the left, is a bit difficult to see the direction and the lenght of the offroad vs the driveable road
the turn into the springs is really really weird and even if i get it right at first time lacks something else to point that you must go there, feels like a dead end when youre reaching it.
Inferno Citadel -
the turn before the path split with the offroad in the left and an arrow pointing to the right clearly said that going right is the right direction but but the arrow points to a wall and the offroad isnt that clear to be offroad can see much people taking the wrong direction
Metallic Hallways -
the conveyor belt turn, i took the wrong direction twice until i realized i should go right, something about the direction it goes, had a big feeling that was the right direction and what got me the most was the lonely sneaker panel that most of the time are located in the outside of the turns a arrow would help a lot there.
and next and last the diagonal springs cut, is a nice cut, i like it but is so easy to miss it, not totally your fault since vanilla springs arent that good for kart, but i had to try 4 times until i realized i shouldnt press any directional button to make it work and even then when on groun again theres more springs to place you back to the track that can be really messy
other than that these are neat cozy maps good texture and readbility even if few smol issues always love your work.
