What is the hardest gauntlet demon?

The list is from hardest to easiest IMO.

Demon Gauntlet:

1. HeLL - the first wave is really annoying and inconsistent and the second ship has some hard timings, especially the orbs. Later the it gets significally easier but it's hard to get good at this level due to the massive difficulty spike in the beginning of the level. The last bit is also pretty stressful.

2. Sidestep - some people say it's easy but back then I had a lot of trouble with this level. This one has a pretty odd difficulty balance and the ship at 70% has some annoying timings. The last ship is also pretty stressful and it's easy to die there due to pressure.

3. Mechanical Showdown - this level would honestly be an easy demon or even 9* if not the bits in the middle of the level. The mini UFO timings are pretty precise and the mini ship may be a little hard if you're not going for the coin. Some people say the dual is hard but it's not too bad once you pass the part with the two little jumps. I never died there past 79%.

4. Vibration - except the last ships with the jump orbs, this level is pretty straightforward and a simple easy demon. I don't like the UFO spam near the beginning though, it's a bit weird.

5. Traction - this one is pretty much the easiest and most fun one of the gauntlet. It has simple patterns and once you get it, it's not that bad. I also like the gameplay, it's quite fun to do.


Doom Gauntlet:

1. Nowise - I honestly think this level doesn't fit the gauntlet, it's a bit too hard IMO. This is like a very solid medium demon and it may be really difficult for an average player. The gameplay also seems to be a little annoying at times (like the spider part) and I don't like the sync of this level, it's below average.

2. Shrill Hallway - I don't know how did it get into the gauntlet but the gameplay looks horrible. I tried it Practice Mode and I was like "screw this level". It's kinda buggy, has weird timings in some places, has some artificial difficulty (like the blinking in the fast cube part), and overall it's a bit too overwhelming for an average player.

3. Darkness Keeper - this level won't be too hard if not the huge amount of memorization caused by the boss fight. I wish there would be more indicators and they'd pop up a bit earlier because the forced memory kinda makes it less fun. It looks great but the gameplay is not fun.

4. Extinction - it's a pretty simple typical level which was quite fun for me and not too hard. Some gameplay choices were a bit questionable (like the wave spam in the middle) but most of it was pretty fun and not that difficult. I also find the wave at around 30%(?) to be overrated but maybe I just got consistent at it pretty quickly.

5. Buried Angel - honestly this is a little easy for a demon but I don't mind it. The gameplay is pretty enjoyable and I like the design and style of it. At least this compared to some other gauntlet levels had some decent sync.

Personally, I would rate them like this (hardest to easiest)

1. HeLL: The wave gave me a ton of trouble. This is the only gauntlet demon that took me over 1K attempts.
2. Mechanical Showdown: This is probably the strangest placement I have. The level was a mess. The ship parts were tight (I beat it when I couldn't straight fly for crap), the UFO had crazy timings, and the dual was rather difficult. Wasn't happy that I had to beat my least favorite gauntlet demon 3 times (or maybe 2nd least favorite next to...)
3. Nowise: Just overall not a fun level. Not sure why I found it difficult.
4. Shrill Hallway: The ship at the start is what made this level hard, but even that wasn't bad. Some people hated the blinking, but I personally liked it (terrible gameplay but fun for me lol)
5. Darkness Keeper: Aside from the 1st coin and the robot part, it was pretty easy once learned. (There is a huge difficulty gap between this and...)
6. Sidestep: Would be further down on the list if the rest weren't so dang easy. The last ship is super ea... (gets shot)
7. Traction: Takes a little skill, but is a pretty fun and easy demon.
8. Vibration: Super easy, but relatively annoying in places.
9. Extinction: Aside from one tight wave, it's not a problem.
10. Buried Angel: Another one of "Robtop's favorite insanes" - AKA ultra easy demon.

I haven't gone through the entire Doom Gauntlet yet, but I would say Shrill Hallway.

For Demon Gauntlet, ofc HeLL is the hardest, followed by Sidestep, MS, Vibration (bug overload), then Traction.

Doesn't matter to me because I'll never beat any of those four anyways ;-;

But Darkness Keeper is probs the hardest, second being Nowise, then a tie between HeLL and Shrill Hallway for being annoying medium demons with cancer gameplay.

Nowise and Darkness Keeper. Tbh I don't consider HeLL, Sidestep or Shrill Hallway too hard.

Yes.

I think Shrill Hallway is hard because I'm unwilling to actually try on that level because of how terrible it is. HeLL is way easier than people make it out to be imo, because the first wave is the only thing making it a medium demon.

I haven't beaten any of the Doom Gauntlet levels, so I can't really say anything there.
For the Demon Gauntlet, from hardest to easiest:
1. Sidestep
This level was absolute hell for me. The gameplay is extremely un-fun, the ship parts are trash, and the end is extremely stressful. IT TOOK ME SEVEN MONTHS TO BEAT THIS PIECE OF SH*T!
2. Vibration
Fun medium demon, I don't have much to say about this level.
3. HeLL
Would be an easy demon if the first wave part didn't exist.
4. Mechanical Showdown
This is barely worthy of demon difficulty.
5. Traction
This should not even be a demon, harder 7* maybe.
