Yes, people should play this level. It's very interesting.

My impressions after three playthroughs. Artistically very pretty and cool, but suffers from poor readability for actually playing as a track.

Snow area is mostly fine. The bridge doesn't have a good indicator that you need to just jump/float the gap. The arrows used usually indicate a wall-run or hard turn. I was expecting some other built in way to cross the gap, but there doesn't appear to be one. The obstacle itself is fine, but it's indicated poorly.

Then we get to the aurora-track. The bit in the snow area doesn't have good contrast against the white, making the wall transition tricky to read at first glance. It's not difficult when you know its there... but that's a lot of the problem this track has. Many things that aren't too bad, if you're both expecting them and know how to handle it already. Making it more a matter or memorizing obstacles rather than being able to play and react well to things.

The Aurora area is honestly an awesome concept. The aurora in the background really brings it together in a nice way. The track itself suffers from being so etherial and not having solid borders. It looks pretty, but it's not always very functional. The first 180 twist transition into the loop is particularly deceptive on first playthrough, since you see other parts of the track before the actual transition comes into view. Makes it hard to judge what the heck is going on and what you need to do on short notice.

Generally, this section can be a little unclear where the edges of the track are. Lacking good reference points when you're focused on what's ahead of you. Second big problem point would be the booster into the long jump. You can't see the landing at all until you're airborne, and it's extremely easy to totally miss the track. Making this feel like another case of "Just know where you need to go ahead of time" Which doesn't work if its the first few attempts.

The long, mostly-straight run on the aurora-track is hard to see what's coming up, as the track kind of blends into itself. Even with the arrows indicating the side of the track, you're moving too fast to really react to them properly. Can't see far enough ahead at the angle the track is moving.

I find the cave portal dumping out out where you have to make a sudden hard turn to be odd. Cool idea, but awkward in practice. Perhaps just having more space would help here? Not sure.

Cave itself suffers from the dark atmosphere. Again, a nice artistic choice, but hurts playability.

The little underwater section confused me at first. The drop down into the water doesn't look like water at all. More like going into the fog, but then the sounds change, and after noticing the fish, I figured out what it was supposed to be. Coming up out works fine. But the drop down into it just doesn't work well visually for me.

Then there's the inverted jump past the big green glowing bit... I really do not like this obstacle. You don't get much time to see it in advanced, there's surprisingly limited room to pass safely between the big obstacle in the middle, and not bump into a stalagmite instead. Also the indication for where you go after that I found to be confusing. I genuinely thought I was supposed to land on the underside of the track after that. Then was even more confused when I couldn't see where the heck I was going until getting thrown off the track into the darkness.

After that, things are, well the jumps come up fairly abruptly, but I think they're alright, since they're not too demanding.

The exit of the ice cave is another great looking set-piece. The lake itself feels a little homogenous, without much going on. Perhaps this is a good thing since it doesn't distract from the owl and the train. The problem is, the actual track/path to take is really unclear, and if you miss it, which I did the first time, it's almost impossible to find from any real distance away. Needs more clear sign-posting for the cooldown pads that lead to the finish.

Utlimately, you get a lot of points for the artistic aspects of this track. It lacks a lot in the functionality department. I can't call this a good track, but it's a very pretty one.
