Don’t play this. This level is actually just awful, easily the most unbalanced and annoying gameplay I’ve seen in a while. Also got ridiculously unlucky, dying 10 times past 80%. Insane demons don’t often take me more than 2000 attempts, but it happened here. It’s not even a hard insane demon, it’s just awfully inconsistent.
Enjoyment: 1/10

I cannot believe I fluked this level from 18%, this is by far my best fluke, especially considering I was quite inconsistent at the ending, 72%, the dual at 62%, and a lot of other stuff.
Anyway, this is level is absolutely amazing (currently my 8th favorite extreme demon), I love how dynamic and energetic the drop is. Moreover, I greatly appreciate that Jenkins always gives his levels a theme, which is incredibly well executed in this case. You should definitely watch this level in full detail: https://youtu.be/Dbl99ctIc_E
The gameplay is fantastic as well. It is fairly difficult to learn but once you get it down it flows exceptionally well, not to mention the learning process is also quite fun. There are a few awkward sections here and there, the spam at 72% and the dual at 62% for instance, although the latter gets relatively consistent after a while.
Overall, this is a phenomenal level that I would definitely recommend — Im glad I beat it as my 20th extreme demon.

Not a bad level, the first 25% is really annoying though. I also dislike how hard it is to see the spikes at 45%. The drop is extremely fun, but I’m not a fan of the ball part at 80%. I would recommend this level if you enjoy skill-based gameplay.

This level looks incredible, I love the theme and the execution is absolutely fantastic. I honestly dont know what else to say, this is awesome. I beat this using the LDM so you should check out the showcase: https://youtu.be/sMav38fd2mA
The gameplay is incredibly fun and the sync is insanely good. I still have a few issues with it.
- The predrop is by far the hardest part and constantly dying to the first few clicks can get a bit frustrating after a while.
- The yellow orb at 17% is quite unintuitive, I died there a lot.
- In my opinion, the yellow orb at 26% is the hardest click in the level which means its very inconsistent, I died there about 60% of the time.
- The UFO at 56% feels slightly awkward, especially the first few clicks. Not a major issue though.
- The ball at 85% feels a bit too hard, especially the first blue orb.
Otherwise, this gameplay is pretty much perfect.
Difficulty-wise, this is definitely an extreme demon. I would say its slightly harder than Acu and easier than Klutz (yes, Klutz is incredibly hard for me).

Really cool level, I love this classic 1.9 style. Decent decoration for its time although its nothing special. Nothing much to say here.
The gameplay isnt anything amazing but I couldnt find any flaws and my experience was basically perfect so I gave this a 10/10 in terms of enjoyment. As you can see, I have a ton of old attempts. I tried to beat this level about 4 years ago (I failed) so it feels nice to finish it off now. I also fluked this from 52 which is nice but not very surprising, this level gets very consistent very fast. Would definitely recommend if youve already completed a few insane demons!

In terms of gameplay, this level is absolutely incredible. I had a ton of fun learning and beating this, its incredibly consistent and satisfying to play. My favorite part is definitely Jeyzors, feels awesome to play once you know which orbs to hit. Sumsars part is also quite fun although super stressful because its at the very end. The first ball was actually much better than expected since you only need to time the first click and then you just buffer all the other ones. Its a pretty tough timing that still gets pretty consistent. Overall a super fun level.
The decoration is pretty good for its time in my opinion, it all feels well polished and I cant really name a part that looks bad. Its also pretty cohesive overall. Lastly, this is my 40th insane demon :D
