April fools special 

ol you cant just release the next 3 parts of black heart like that

Im sorry *w h a t* is happening here my eyes cant handel it

Man, we uploaded April Fool vids at almost the same time. Lol. 😅

the okayest collab saga is just awesome

im quite disappointed you never showed these on youtube until now smh

Isn’t that background the default background in the editor? Fantastic I love it 10/10

This level hurts me in every way possible, what a nice April Fools special

These are most likely the "best" levels in Project Arrythmia yet. The thumbnails, artstyles, animation, the attacks... You all are SO TALENTED! >:D

Movimientos epilépticos el videojuego

3:21 that's my favorite 😂😂👌

this is just too funny lmao 8:22

I feel nothing but pain

3:22 that’s a portal to the void

My main question is just WHY did you have to add that part at 2:49?

8:21 My New Favorite Project Arrhythmia Level Lmao

its 12:30 rn and i think my brain just deactivated

lmao 3:10

My eyes are Burning but April fools day! And how do you have the game running not laging with so many Bullets

The last one that you missed was actually almost pretty good

Imagine if u made the thumbnail look like it’s the next black heart level and they click on the video only to see 0:00

1:33 Me: this sounds like in... Goat simulator? Everybody: what did you say?!

2:48 seizure boi z:D

Wow... even the april fools special is really awsome

This is the best level created (lol)

Happy April fools Ol! This isn’t a joke for real! You’re doing amazing :D

3:21 my fav part lol

This comment isn't related to the vid but a "Time" related boss in the Blackheart lore would be awesome. Segments of some of the pass bosses would be cool, but Mutant and song of storms the exist so it's unlikely

i knew TNTZ was helping since the video began... somehow

Crazy train is crazzy already the bosses what the bru i cant see anything 😂

amazing

I just woke up a second ago... I’m neither having a seizure or this isn’t what my body was expecting.

hey dude remember that one ol666 lvl that crazy train had a spasm? wait wut
