My story with Ultrasonic began even before this level was released. I made a level called "UltraSonic" in early 1.9 and it became my first rated level (because of Sumsar I think). That's why thumbnail has parts from two levels 8) Sorry for some noises in video, I recorded this in my parents' house and couldn't find any silent spots at that moment :/
---
I began playing this level seriously in 2017, same time as with Alphabet X. Had 49% for some years, got to Evasium during this Spring. I was right with my prediction of lot of deaths at Sumsar, I eventually died 22 times there, probably biggest amount of fails I've ever had at the end of a level. Worst fail was at 97% but ten minutes later I beat this legendary insane lemon. GG :) In my top 5 hardest level completions for sure. 31 000 stars and 645 lemons also with this. What should 650th be? 8)
---
About the level: A classic megacollab and first Sonic -level I've beaten. Level is a bit unbalanced since the hardest part for me was the very last one. I died around 200 times after 60%. Still, my experience wasn't only terrible. Ultrasonic is pretty fun level to play. Designs have aged pretty well in my opinion. My ranking of parts from hardest to easiest: Sumsar, Evasium, Glitter, Gboy, Jeyzor, Zenthicalpha, Viprin, Xcy7

Two phones and almost 18 000 attempts later, I did this. My first extreme beaten in 2.2. Second mobile victor and first on android and HRR. Going to beat my next hardest after this, which I will announce soon... Also I really have to get some 2.2 levels out as well lol
Ive already said this multiple times but this was the level that killed my precious Poco X3 Pro. I was playing this in November 2023 and during that session, game froze, system froze and phone turned black and wouldnt reboot itself. I lost most of my photos and screenshots and videos because of that :/ But it was due to faulty motherboard most likely and the phone had been rebooting itself for no reason for a while before it ended up totally dying so it was just a funny coincidence that it died while I was playing one of the most demanding levels out there.
So, I ordered an outlet version of Xiaomi 13T so I could get it for as cheap as possible. Bought it because of 144hz but it only works if I turn off all system optimizations and this level really needs optimization so I kinda had to beat Quaoar on 120hz. But I might utilize the 144hz screen in the future, tho. Shoutout to DashY for providing a tutorial on how to unlock 144fps on this device.
On Poco X3 Pro, Jenkins lagged extremely much and I wonder if I couldve ever got this level beaten on that device. On Xiaomi 13T, this level lagged as well, but less and Jenkins was tolerable, despite still dropping frames. Framedrops were present in multiple parts and they seemed to appear randomly.
My experience: Began this immediately after Subsonic. Played for 2 days, then my phone died while I was playing this level so couldnt play it for a bit under month or so. Started playing seriously in early January but couldnt get it done until now. Was pretty unlucky but luckily died only once at 86% and not at all after that.
About the level: Great looking, sometimes fun to play but agonizing during long sessions when you just get stuck in certain parts and cant figure yourself out of mindblocks. It doesnt also help that the level is very unbalanced, some parts are easyish while some took literally thousands of attempts to get done (Flash, Jenkins)
About the difficulty: A lot harder than I thought imo. This actually took more attempts than Subsonic if I count the attempts I lost with Poco X3 Pro (around 3000)

Attempts: 9 530 (online) + 5 403 (copy) = 14 993 attempts (I had around ~3000 lost attempts so 17 993 in total?)

Harder than Subsonic??? maybe not but this is underrated and probably harder than DARKENED and Sigma Interface

Not really an insane lemon but yeah. JHdash77 challenged me to try this so that we could know if it was Finnish mobile list worthy. Both agreed it wasnt :P Beat this one without a copyable so thats something I guess.
A new Hinds level should be a good thing but Im kinda mixed on if I like it or not. For some reason, after playing it for longer than 15 minutes, my eyes and brains began hurt lol. I guess its fitting for the levels name and my mind isnt master enough :P
About the level: Visually it looks pretty good when just watching a video of it but the experience of playing it yourself wasnt the best for me because of its weirdness. Nonetheless, very unique and indistinguishable Hinds design. The gameplay was good too, Id say, but I had too many stupid fails which made me rage every now and then.

A quick hard lemon done. My first JonathanGD level completion which is weird since I have known him since early 2016 and Im also among the dedicated people of this level 8) Its a great level still and I fluked it from 67% get rekt John 8) I even died to 99% only two times overall when I practiced the level, it wasnt even that hard of a click lol. Was trying to get all coins but somehow forgot to jump for the second without even realizing it plus I was too scared of dying at the end so I decided to not collect the last coin even though I had practiced it
About the level: A level that is already 5 years old, has aged pretty well. Design is good and the gameplay as well in almost all of the parts. The level is maybe a bit too long for my taste, plus the last coin is ridiculous because its RNG

1000 moons, fifth platformer lemon and first platformer extreme. Took around 25 hours of playtime in total. Last Friday, I tried to get this done in the first try and after I got to room 1328 after 6 hours of playing, I took another break but GD decided to reload itself during the break.
About the level: It has rooms. Yeah, a bunch of them. 2024, actually. Some are harder than others and some even help you at losing your sanity. All equipped by wonderful music from Kevin Macleod, whats not to like?
My experience: I overestimated my skills even though I know I suck on platformer. I shouldve not tried to go this without any practice because the video wouldve been over the limit what youtube allows for lol. If you are not an expert in the platformer mode, I recommend try doing at least all of the rooms in Hypnosis Trials in a copy with startpos. Those are the hardest ones and if you cant get them done (in a reasonable amount of time) theres no reason to play the level. Also, in the Speedrun Trials, I had to use an external device called spoon to be able to have all my fingers free for spamming instead of having the other hand used to hold to left/right
My sessions:
First try: 6 hours, rooms 1-1328
First practice run: 4 hours
Hypnosis trials in copy: 6 hours, rooms 1815-2024
Missing rooms in copy: 1,5 hours, rooms 1300-1815
Second practice run: 3,5 hours

I underestimated this one as it took 800 new attempts. Still pretty easy for an insane lemon I think. Also the song is great. I have a couple of videos of ViPriNs hard lemons but idk should I upload them one by one or just combine them to one video or even spare them for potential advent calendar lol. Im also very close to 800 lemons, I have atm 793 :D
About the level: One of the last levels that had the same block design throughout the level. Looks still pretty good imo and gameplay is fun but challenging, therere a lot of timings in this.

I wanted to beat something special for my 30 000th star so I first decided to try Corrosion by Killa & more but then started to play Crimson Clutter for fun and yeah. This happened. My second or third hardest lemon. 31 518 attempts. Is this another world record of attempts for me? 8)
Originally I used to play this back in high school but didnt make it further than 32% or something lol. Then a month ago I reached 29 990 stars and started playing this seriously even though it wasnt my initial plan. A week ago, I had like 5 deaths after 45% and my record was 59%. I was hoping to fluke it because I was pretty consistent. But I died at 82% and then I started to die after 45%. A lot. Really really lot. At the end I had 136 deaths at 45% or further. Luckily I didnt die another time at the last ship. But oh boy that 1-attempt-practice run hurt my soul 8) Basically I beat this trash twice during the same day and on phone lol
Sorry for another camera-recorded video, but my phone is trash and I couldnt optimize settings to be able to record the screen without lag. But at least I beat it in the exact same spot as I did The Ultimate Phase 8) Also, I beat this 10:35pm on 31st of July 2020 so now Ive beaten insane/extreme lemon every month since April!
April: Alphabet X
May: Leyak
June: Acropolis
July: Crimson Clutter
August: ? 8)
About the level: A Nine Circles level. What else to say. Apparently the hardest NC level beaten on phone if we exclude 90/120hz phones, correct me if Im wrong. Sometimes this level is very satisfactive but usually it just annoys you. Its nearly frame-perfect in many spots and dying dozens of times at some single timing gets frustrating. It can still be fun though, when you succesfully pull the parts off. Design is also a mixed bag. Color combinations are not terrible, but they are so dark that it makes the whole thing harder to play and enjoy. Dont even try to play this on sunlight 8) Its impossible

Best part: Last ship is fun and kinda easy so maybe that
