Hey man! Cool level!
Level difficulty: 4*

Review: This level is fairly easy, but has some pretty cool gameplay. Needs some stuff to keep it less bland. I'll go through each part one by one:
    Cube: This part is way too easy and does not compare to the other gameplay in the level. It is very repetitive. If I died on the fourth spike, I would think "This entire levels going to be jumping over singular spikes". Add some jump orbs or switch gravity to make it more interesting. The music sync is really on spot though. Design is bland here. All there is is a few blurred spikes, and a weird background. For something like this, really work on the background because it is really open and stands out.
    Ship: This is where it gets good. The speed change helps keep the level interesting, and is a very smooth transition. The straight fly isn't too hard, and it kinda feels like you are beating a really, really nerfed part of an extreme demon. The saw blades could be bigger, as it feels too easy. The portals flow with the level and the music sync.The background is really cool here. No idea how you did it. Block Design needs some work, as it is just some blocks around since 1.7.
    Ball. This feels even more like beating an extreme demon. Unfortunately, the music sync is off, but it has the best gameplay in the entire level. Not much else to say. Same goes for design. A little mre effort put into block design, but not too much. Background feels rushed and messy.
    Rest of level. Robot has some cool gameplay, but feels rushed. Background is pretty cool. Needs to be more dynamic though. Wave needs to be shorter and be way less repetitive. Maybe put a UFO at 74% to add variety? It would flow well with the music. No block design, just Invisible blocks. Design is pretty cool though.

Would put in decent levels. I feel like you rushed too much on design and near the end. Still, OK level.
