Project Arrhythmia [Custom] boss: Kaixo - Alacrit 

weird bug at 3:10 and no, this isnt a part of black heart

every single music level maker ever:"see that cube there? "let's make it suffer"

This level is literally so amazing I can't even describe that

No one: ol666: video length 4:20

Beginning: general concern for nowo Halfway through: wow this is my kind of shape

Another amazing level- And- wait is that Nowo?! . . . Being a PA character is suffering . . .

I love the fight with Colatric, the music and design make him look more aggressive compare to Nowo, who is trying to take back control. Even when Nowo's face is on screen you can tell he's still not in control of his body. Also I don't know why I just love how his mouth sort of moves to the beat of the song, especially in the chase scene looks like he's trying to eat you.

It seems like Ol666 is no clipping throughout the whole video even at 3:10 but he said it was bugs so I was wrong XD

What is it with the square abuse? Sad boi (JS&B) Nautilus, then NOWO. Edit: Sad Boi *Close To Me* Nautilus *Party Time* NOWO is the boss's official name from the level Opia. Edit the square that suffered the most is the player. The player is a square. And they have to suffer countless brutal attacks day by day.

I love the animation on this it’s so smooth. You’re really improving each level. Also this seems to be a different story that involves dead locked. When it says 4 left at the end There’s probably gonna be 4 more to this story

Nobody: My brain: we don't need no sleep because the party don't stop-- oh wait oops Also my brain: CLOSE TO ME CLOSE TO ME *bass sounds* CLOSE TO MEEEEEE

Uhhhhh does it say 4 left its scary. Also nice level ITS AMAZING

OMG That's Epic :000 ¡This level is really amazing!

Disclaimer: This is not part of the black heart!

For just 50 cents a day, you can stop these poor square bosses from being abused and possessed. Stop square abuse today.

Everyone who played this level: Yes, I finally beat it! Ol666: There is another.

Omg this is one of the best levels i've ever seen😳✨

Wow, This is... This is Perfect, What a Surprise That You Have Finished it Now, Mecha Sure is Proud of the Result :D PD: IT'S FINAL IS SO CRAZY!!!

Wow a new character and it looks amazing

Yay. I love all your levels cuz their vizuals and style look amazing.

I- I'm speechless. This is amazing!

I was literally On The Workshop To See If This Level Had Uploaded Yet When THIS Was Uploaded XD I also realized that Every Time Scribbs Uploads a Video, you Release A Level Within 24 Hours Afterwards XD

This should be a start to a prequel or something, This needs it's own story

Nothing: No one: Not a soul: Me: *but the end tho*

awesome :D those animations where soo smooth and creative.

Pretty cool idea with the references to Opia.

Damn coming back to this level and it’s gotta be one of my favourites if not my favourite. Everything has a lot of energy to it in the drop. Put it along with a outstanding thumbnail by Starrlet and you have yourself a cube torture filled masterpiece! Really outdid yourself Ol!

This is amazing At the start I thought I was at the wrong video What I thought: is this opia? Oh wait, no.

_nowo has joined the gang of being a suffering Cube turning evil while trying not to_

Close to me but Opia got controlled instead of Cube or Nautilus Edit: this remind me of Geometry dash icon

This was the first level of Project Arrhythmia I saw back in late January of this year. Thx you for the amazing introduction to both PA and games like it as well as being a source of inspiration every once and a while

I didn't even noticed anything about the bug lmao- Animation and transitions are so well made and so smooth liKE BRUH THAT LOOKS EPIC- Can't wait for the next level of black heart tho qwq

3:11 Zen Mode Confirmed

"4 Left" Me: "4 Left"? Also me: so theres more 4 levels? If the 4 means 4 levels, what are these levels, and... if we beat these 4 levels. What will come next...?

This song is definitely going into my new series, the INK-pocalypse (it's coming soon)

Another amazing level! :D

Daaaaaamn this is absolutely amazing! Great job! OwO

O_O I honestly have no words for how good this is And at the end it scared me a bit for when it said 4 left

This is my favorite level on PA! This is amazing! Great job!

Nobody Literally nobody Ol666: Allow me to introduce myself. I'm the Cubes grimreaper

Me: **almost halfway through the video** Also me: *Nice to see ya Close To Me.* **starts singing Close To Me**

It's very cool! New sub

ANIMATION IS SO SMOOTH OMG

The song and the level are so synchronized, it becomes satisfying

Used to listen to this song now I just have to come here

Another masterpiece, good job.

These Boss animations are so dang smooth I love every part of this level and how it was made! It looks alot of effort was put into it to perfect every part and sequence of it and doesn't look like a lazy effortless level it actually THIS here IS a BOSS BATTLE! Especially those Equallizers they actually work how an Equaliser is a post to work Outstanding job on whoever made this level

This was an epic song! Nice job completing it without taking a hit! Keep up the good work!

I'm never gonna leave unimpressed after watching any of levels that you worked on, i absolutely love the animation! I already said it about a million times before, but dude how do i comment about this without repeating myself! I'm legit gonna buy project arrhytmia with all my saving as soon as i get enough and play all of the levels!

This kinda reminds me of that sad Boi in jsab and in the level close to me. Also this level is very amazing. The faces of now really shows how hard it is for him to try and attack the square. Hopefully Nowo is okay.

This is as fluent as every level you've done/helped with so far!

Amazing! A beautiful lightshow indeed! ^^

I though it said “No OwO”

Yay a new boss out by ol ! :) love your levels

this is awesome, great work!

Wow this is amazing? Keep up the awesome and creative content ol666!

Judging by the ending, here is my prediction: Each level of this pack is going to have something to do with a non-black heart character being controlled/corrupted by Complex. (ex. Lumi, Kit Kat, Coal etc.). The last level of the pack may be a fight against Complex himself.

OMG! I love this so much! I also love the Opia theme at the beginning!!

omg I love this level

This level is really creative keep up the good work ol666

FANTASTIC LEVEL!!! 10 OUTTA 10!!! The patterns are just so cool to look at! And I LOVE how you used the original attacks from Nowo's first song and morphed them into something WAY more difficult! It's kind of like Opia on "hard mode" except 90% of the attacks are not similar at all! Great job, ol666, keep it up! Edit: Also, "4 left?" I wonder if that means there are 4 more old enemies that are going to be greatly improved as well...

Absolutely Stunning!

Nowo: Help! I'm being corrupted against my will! Cube, Puffer, and Nautilus: First time?

Really cool and epic! Love it! ;D

Amazing Level!!!! Now I Need To get PA Sooner rather than later. I just need the money

Nice poor nowo I he was just sleeping

I can't believe this amazing thing is the first PA boss I've watched!

This is freaking amazing :O Also #StopSquareAbuse

I love how the Opia boss is now turned dark and it still keeps aspects from it's old fight. The twist was amazing and the ending only leaves more questions... Congrats on the collab and keep up the good work.

This must be par of a series. Perhaps deadlock.

This character an innocent Cube turning bad reminds me if Cube from JSaB

AAA tsym for finishing this ol!

"4 left" is this gonna be the square torturefest or some other mini series of doing stuff like this to other levels? Those are my 2 guesses

God these movements are so sMOOTH

Its so soft when moving i love it :O

Loved it. ;)

EPIC LEVEL

he’ll yeah gamer time

HHHEEEELLLLL YYYEEEAAAHHH >:D

Is curious, i have never played pa but i like the levels that you do, i love you 💙🇪🇨

Thats really cool thats look like thats new

Dude, it's so epic. It's will be my favourite boss, 'cause its gameplay and effect is so fun. I love it!!!

This is the first boss I've watched from this game, and I wasn't off to a bad start for once! That's how good this game is **clap of quality**

Nowo = My positivity and happiness somewhere inside me Coalatric = My Rage and hatred being exposed because 5 bad things happened to me The box thing = Somebody pissing me off

Hey, Ol, I don't know why there's always people who dislike your amazing vids. But I think they think this is a rip off of Just Shapes and Beats. But if any haters see this comment... GO AWAY! And also, by the way, this on 1.25 speed is legit *F I R E.*

Do you have to verify these before others can play them or is it just like _"I'mma just leave this here"_

Nowo? whats this? (sorry had to) amazing level design. I could watch the beat drop for hours and still not be sick of it lmao good job

OMG how did you make this?? i have been waiting for the level and i cant wait to play it myself it!

Woah cool level So whats the name of the coming black heart level

Is it me or the song sounds like to Nitro Fun - Cheat Codes, thoughts to little different? 1:10 Well, I mean that's, the rhythm sounds the same And by the way, ol666, I love your project! :)

Hmm... If I had to choose a favourite part of this level, it would have to be Colatric's eyes. You've put so much movement in them it's amazing, and it add that special something to the level that wouldn't've been there if you had left the eyes static.

This is your best level in my opinion

The level in a nutshell: opia but its close to me

Wow, cool level

Fresh:jest ya need to speed up ya game” Geometry dash character:yeah” Jester heart: *points at predator* how’s that for speed up?” Fresh:nevermind”

Corrupted Sad cube: *See That Bossfight* Also Corrupted Sad Cube: I'm a Joke to You Nowo?

Im speechless but very NOICE!

Thats really cool

NEW!!!!!!! THANK YOU OL666😭🤩🤩✌✌

OMG this is amazing
