I beat Feral a while back when I was beating random insane demons, and what can I say, it definitely doesn't overstay its welcome. Feral clocks in at about 40 seconds and makes incredible use of its short timeframe.

It's a very simple level on first glance, really only containing a couple of colors. Black, red, and orange, but the way these colors are used in conjuction with pulses and the effects makes it a genuine feast on the eyes (I keep using that expression for some reason LOL)

The unconventional song really sets the tone for the level from the very beginning, it's already something that almost nobody would be expecting to hear in a GD level, and yet this level fits it perfectly in my opinion.

The level starts off very slow for a couple seconds, showing this waning glow in the background showing the structures in sync with the song, before almost instantly throwing you into a 4x speed robot. You are instantly assaulted with rapidly flashing red and black colors as these lines in the background seem to be shaking and curving all over the place. The lines in the back reminds me of a heartrate monitor for some reason, and it stands out to me a lot. Everything in this part just moves extremely fast past you, so much so that it all kind of blends in with each other. I can understand why that is for a level like this, but I wish I was able to see some parts of it more. I also really like the spinning x's in the blocks LOL

The next part just ramps up the intensity even more, with the background going into complete chaos as all the blocks and structures start to break open. It's like an effect of when you reach a floating point in a game, definitely not the intention, just an observation. It's an extremely cool effect and definitely fits the chaotic nature the level is trying to go for. I also really like the UFO parts where you hold your wave through them and these spikes with decoration appear on a pulse. It's slightly subtle, but it really sticks out to me in this chaotic mess of a part. (Compliment I swear LOL)

The next part brings it down slightly in intensity, while still keeping it at the same speed. The structures are much more visible and put together, however the background is moving even faster and the objects are rotating MUCH faster. It feels like you literally can't keep up with the level anymore despite being at the same speed. I also like the really subtle white flash on the dash orb where everything seems to stop at the moment. It's a very small moment of the song which I'm glad they highlighted!

The part ends with the background going black and you jumping on the numbers 1, 2, 3 , and 4 in sync with the song which I LOVE. I love interactivity with songs like this and I think so many more levels should do it. Having lyrics or song representation in your level is cool, but having you INTERACT WITH IT is so fun. The level slows down vastly after this, switching to an orange color scheme at this rate that flashes red. This part's atmosphere is absolutely crazy. It keeps the same waning glow effect from the beginning and after each measure, the gameplay moves up by 1 block. It keeps it SUPER interesting, especially for the end of a level like this. I also love the zig-zag floating spike structures that only appear on the pulse that moves the blocks up.

Feral is an incredibly well made level that fits the song super well, I love all the effects used in it and I feel it fit's the intensity that the original song artist was going for. I just wish that it was a bit longer personally and that some of the effects didn't blend in with each other. That's just a small nitpick though :)
