Re-Rank will involve the two levels FrozenTrepid and Industrial Consumption, and it averages out to C tier.
FrozenTrepid (B-) is a level that has a neat gimmick. However, it has two major flaws as it overstays its welcome and that there are messy places that feel way too cramped. I like the creativity of the level, but this level could have been condensed a lot longer.
Industrial Consumption (C-) Honestly, this level would have ended in D tier if it didn't have creative aspects to salvage it to C-. I legit quit playing this level due to becoming really irritated with it. I really love the gimmick but outside factors really affected my mood playing this level. The level length-wise does not feel like it would overstay its welcome so that is fine. The main issue is the graphics in this level, in both sections there's so many effects that it is hard to see what exactly is going on or to keep your eyes on. There's two effects, background, foreground and enemies to look at and it's way too busy. The reason frozentrepid is better was because it didn't seem to have this issue. The sledge bros inside of blocks took a while before I realized they were there. In addition, there's different shadings of the wooden planks which I had to guess until I learn what they'd do and if did incorrectly, I would just die from misinterpreting. Moreover, in the darkness section, I could physically not see a lot. For example, there's leaves that break after you step on them and I did not know about them until that. Meaning I fell down and got softlocked from breaking a bunch of wooden planks. Moreover, the darkness effect in the 2nd section is physically impossible from some pcs to see through, so it was way too frustrating to deal with. In the next section, I think there's some issues with clear pipes but I placed a saw to the right of them and they teleported away for a bizarre reason, so this level does not function properly (Im not holding that against the rating). Im just saying after that I was too irritated to continue playing the level. The level in the current state is the definition of wasted potential.
The sound-effects are way too loud compared to the music, so that needs to be toned down. Moreover, the turn-around sound is actually abysmal; it's the effect where you scratch a chalkboard and it's loud so it actually hurt my ears to play this level.
Aside from that, some of the default settings actually mess up gameplay in pretty bad ways. The ground pound here, is accomplished by holding down in the air. This in effect means that you freeze where you are. However during smbx sometimes you naturally want to press down while moving airborne, so this interfered with base gameplay to the point that it actually did not work out. Please have this mapped to different keys or fix how the ground pound works. The wall jump here is fine except for the part that you start in a wall jump state when you're not pushing against the wall, causing easy and unfair deaths to the player.

Industrial Consumption (B-). I finished recording the footage for level of the month for your level. I really enjoyed the level creative wise, however the execution was a bit iffy. There seems to be a pattern with your levels that make them sometimes not fun to play. The first of which is that you use way too many graphics in a small space, this makes me have to try to look through effects, foreground, background, blocks, and consistently identify where is the next place. It's not all that clear in your levels and it led to my deaths a few times. Another issue you seem to have is that you want to cram a lot in a small area that's related to the level. This could be done well, but often it is done so in moderation and levels give people breathing room. Your levels has a ton stuffed into a screen, that it always feels cramped and has no breathing room. It sometimes just feels exhausting to play. In essence, you have a lot of creativity, but these two issues are really holding back how fun your levels are not. As an aside, the some star coin placements in this level were not that great. The first one there was no tell that you had to randomly trigger an invisible trigger. For the second one, I thought I had to bullet bill jump since the other option was risk jumping to your death. Overall, I think you've inched your way into the lower part of B-. Keep on making levels.
