Hmm... A decent level you got there. Gameplay: The gameplay is really bad in this level. It's not very fun to play, there are loads of unexpected objects coming at you, or paths that are hard to see, and I also didn't like how little our vision was at the first part. What I dislike the most is the rainbow ship + wave part starting at 0:11. It's VERY hard to see the warning signs/arrows and the movements of the objects are sharp, unexpected and buggy. It's not very fun to play this part, please give the player more time to react to the upcoming obstacles. The movements at the wave part at 0.39 is also very buggy and unfair and the transition at 0:42 is very unexpected. I also really dislike how you can't react to the upcoming cube portal at 0:50. I really like the sync of the gameplay though, I can clearlys ee you've put effort into that!
Design: Hmm... It's nice, but with some flaws. My biggest complaint is how unoriginal the design is and how bad the block design is. The block design is either non-existant or only consisting of black blocks in almost the entire level. The only exception is the first part which has some block design, but it's really boring and unoriginal with only a few decorations. Especially the wave parts block design at the end had non-existant block design and that looked really bland and lazily done. (0:38). Try to experiment with using more types of different blocks and more decorations to spice up the block design. Only using one type of block for block design is not good enough. I get it's an effect level, but it really doesn't change anything. Now the effects are nice and I like the colors, but they're very bland and unoriginal to be honest. I also really dislike how empty the level is, there is literally zero to no decorations/air deco in the level. A level can't only have a custom-BG it needs decorations as well! There's also a lot of copy+paste in this level, and it's very rushed, especially the end where you don't have any blocks or foreground at all. I really liked the rainbow at the end though, and the color combinations and color choices are really nice!
Originality: Not very good, I didn't see much unique in this level really ;3; Most of the design was unoriginal and bland, and the gameplay was buggy and annoying. I kinda liked the orb mashing at the end though, you don't see that too often in the recent levels!
Music Sync: I can see that you've put effort into the sync, good job DECENT LEVELS
