This is way above my skill range so I had to judge a video. I have to say that this level does give the song justice and has simple yet effective effects and pulses. There are also some interesting concepts with the prime numbers, which I appreciate. I do see the inspiration from Cold Sweat though.

Awesome level 10/10

This is a pretty obscure level, that, i'm ngl, I wouldn't even know that this level existed if it weren't for youtube showing it to me the day it was released.

I was already intrigued by the concept of this level which is centered around prime numbers so I tried to play it and yeah, idk how you make decent gameplay out of prime numbers but somehow, Astriiix managed to pull it off.
It starts off with a staircase where the length of each stairs is the length of a prime number minus the previous one. This part kinda reminds me of Sunset Sandstorm first part where the player will slowly ascends as the song gets more intense as you go through it. The gameplay in this part is honestly super fun and is a nice way to introduce the player to the level. It gets faster and harder the more you go up this staircase.
And then it all explodes in the drop where you are thrown into one of the most interesting part I've played gameplay wise. You are facing a fast mini-wave section that is decently tight and long for an insane demon. The catch is, in every beat, your click count has to match a prime number. Pretty simple concept in theory but what makes this super intense is where you have to do that, in the aforementioned fast mini-wave that lasts for a decent bit with tight corridors. Tracking your click count while doing that is pretty much impossible so you have to learn the amount of clicks you need to make which adds so much depth to the level. It's also a great way to make the part even more intense that it already is without making the gimmick too painful and annoying. Also the visuals in that part are crazy, yes the effects are a bit dated but it still looks amazing and the fact that it blocks your sight makes it even better.

Yeah, this level is absolutely amazing, it's so sad to see that it got close to recognition whatsoever and was forgotten by everyone and there is actually a few amount of ppl who has seen it and it's such a shame.

Great map! will try to beat the level in full detail to get the full experience later for sure bc it deserves it
