Hey CreatorGMD! Since you put so much effort into reviewing everyone elses levels so quickly, I thought I would review your level for you.
Gameplay (3/10) - Is your gameplay balanced, fun and interesting?
This levels gameplay can be really repetitive at times, All ship parts in this level are flappy bird level-esque 'fly through the gap gameplay' & these sections take up 20+ seconds of the level! try add some variety to the blocks used in your ship parts & use different styles of ship areas for different parts of the level to make each part unique. Speaking of parts that are only takimg up time in the level. the end dual ball that just drags on with no gameplay seems purposeless & like you just added that to get the 'long' length level. The UFO dual at the end is also really buggy as it is not symmetrical and your duals will occasionally clip the pillars edges wrong and kill you, this part seems to be almost 100% chance. Try to make dual UFO duals symmetrical as it is very hard to make dual UFO parts non-symmetrical & still fun to play. For transitions in the level, some can seem very sudden with the player having to immediately tap twice after a ufo transition (could be fixed by adding a ramp to make it seem less sudden) & a green orb in the robot portal that is almost invisible as there are gravity switch portals beforehand. For things you did well, the cube gameplay in the middle of the level was quite fun & The dual cube also had pretty good gameplay, even if there was a bit of a difficulty imbalance in this part. Other than the things aforementioned the rest of the level had little errors in this category worth bringing up.
Design (5/10) - How well does your level flow? this includes sync too!
This level has a consistent 'cold colours theme' which works quite well throughout the level, You have used basic colour/background variation to make the level flow better and give basic deco sync. This level's gameplay sync is quite good & your everyplay video actually has really off sync. Although the ship parts kind of let you down as the gameplay sync here wasn't very good other than the gravity/size portals.
Decoration (4/10) - How pretty does your level look? this includes effects!
Gonna break this up into points so you can easily see what you can improve in particular in this category.
Block design: A lot of the levels block design allows you to see through into the background, and can make background deco mash with the solid blocks. try & avoid this by making the blocks solid & use layers of other decos to make unique blocks that look nice together. The area that did this best is the UFO area after the ball, the areas that could have been improved on here are the robot, ship & ball parts.
3D: 3D was not used in this level at all, I recommend using it in areas like the cube, Ball & robot to make the ground blocks stand out more.
Copy & paste: A lot of the background deco, All the ship parts, & a large portion of foreground deco were copy & paste. I recommend using the same deco design only a few times in each part & work on varying it to make each part look unique, but still seem like its the same area. Heres a good video explaining variation by the creator triaxis:

Deco Sync: Try use moving objects or pulse objects to make the music pop from a decorative standpoint. Sync isn't all gameplay. There are very few pulse orbs/objects used in this level & I recommend using more as they add to your levels sync significantly.
Originality (Multiplier x1.00)Flat multiplier as there was nothing particularly unoriginal nor particular original.
Total (12/36)
Category: Decent-
Recommendations: No feature + Harder 6
You can definitely pick up your score if you try putting a little more effort into making each part different / hand crafted. Hope you can learn a thing or two from this review and use that to improve on your future creations
And also the ending was completely unnecessary.
