Calamari Coveby: Venexis
Why?: It is hard to dislike this level. Short level loading time does make the expirience more pleaseant, but that is not what we all remember, do we? Of course we do not! The puzzle section is incredibly memorable. It makes the atmosphere greatly for the level. The puzzle system is just a lot of fun....wait what?....this is ALSO the level that has Omega Blooper? Jeez, you are overmaking the awesomeness Ven, stop it :'(. Yeah, this level is just a lot of fun. The first beaches sections are really not noteworthy, but everything else is.

Alligments of Fatesby: Ven and MoD
Why?: I can easily say this is one of the most innovative graphical levels I have seen. Period. The way decor is used in such an awesome way, and the tiling, GOD! It just looks amazing. The gameplay also is at the level, with cool block creatures (cave worms <3) and block trickes all well executed. The story...I am not too crazy about it, but hell, it works well. Very memorable level by very memorable LDers.

Arid Arid Desertby: Foru
Why?:

Only 13th? Yes, sadly. The level is incredibly clever. Clever plattaforming, clever storyline (hilarious as well), clever secrets, and so on. But to me, it never really broke the "clever" barrier. It is a very enjoyable level, in fact, go now and play it if you did not. NOW. But still, I just preffer the other 12 more

Shy Guy's Islandby:
Score ruiner Buffoner
Why?: In contrast of what Volcove told me, I believe easy levels can be fun. In fact, they can be as fun as any challenging level. With clean graphics, superb gameplay and just an overall incredible remix, Buff makes a level nobody should miss. It is a sweet, short expirience. Do not miss it

Darkby: MoD
Why?: Eh....I think it is obvious. An incredibly well told story with amazing graphics and simple yet fun plattaforming. That's about it, but God, I think that is more than enough.

Volcove's sky level series! (Heaven Realm/Parrallel series)by: Guess.
Volcove, genuis.Why?: This is one of those levels I will replay over and over everytime I fail. Why? BECAUSE IT IS FREAKING FUN, THAT IS WHY! Graphics are nice, but Gosh, this plattaforming...it is just what you can expect from Volcove: constant Jaw drap

SMA: Mirror Islandby: Ampli and Sk
Why?: NO, NO, NO,NO! THIS IS WRONG! THIS GOT THIRD, BUFF GOT FIRST. YOU ARE WROOOOOOOOOOOONG!...ok, I know. But this is still my fave entry from the 20th LDC. Every level is unique, and I love the final boss and Hamneus castle. Graphics never fall, gameplay is almost perfect and the blosses are awe in the most pure form ^_^. This series is amazing. Give it a shot. It won't dissapoint.

Explorer guy (nope, MoD is not the only one who likes this series
)by: Zeb
Why?: This level is just a gem of awesomeness. I love the graphics: simple, but well looking nevertheless. I love the story: kewl and funny. But overall, I love the gameplay: original, fresh, new, and block based. The final boss is incredible. Probably one of the most original bosses I have seen. A masterpiece indeed.
Number 5: Into the Depthsby: Volcove
Why?: To be honest...this level does not really what Heaven and Parallel did, this level does frustate me pretty quickly. But for crying out loud, this just haves EVERYTHING the other leveld missed. The graphics look amazing, those block creatures are so well designed!!! The amazing underground construction and going outside to get the silver stars were just epic. The dinamic of the level is flawless...even though it can be frustraiting. And also PQ rocks!

Final Rushby: Murph
Why?: Perfect plattaforming. Nothing else really. This level has absoloutely perfect plattaforming. Perfect challanges. Do not skip on this one. You will loose the perfection of a plattaformer. And boy, it is so much fun!
Number 2:
Destinationsby: MoD and Ven
Why?: Jesus, if AoF was great, this cannot be described with words. The story of this level series is something that makes it unique. Sure, it may be long, but hey, this is the key of being able to enjoy one of the best levels ever made. Not to say the graphics or the plattaforming are bad. NO, NOT AT ALL. Graphically, the series looks very nice, it does really look like a nightmare. And the gameplay...Ven is here, so you can guess. BLOCKS. So yeah, play this level and read the story, you won't regret it.

Penguin Godby: Volcove
Why?: Man...stop it. I can understand having two fabolous levels, but this is just too much. Seriously, cut it off, your levels are way too much fun for me to take it. This level...is just....the best level I have played. The gameplay....boy...that gameplay....I had never had so much fun playing a level on SM63, or hey, in fact, this levels is one of the funniest levels I have played in Mario games in regards of plattaforming. Everything is so well calculated. Dude...seriously...I have no doubt why you are first on the tier.
