Looks really good overall. Here's my thoughts:

It seems like a fitting intro for the level. The gameplay is very nice, it's non buggy, flows smoothly, for both the cube and robot in this part. It works together quite nicely. The decoration is fantastic. While it is simplistic, it seems to fit the level quite alot. Your block choice and background, along with extra decoration, works together nicely. The sync is nice as well, it goes smooth with the song. So far so good.

The gameplay here seems to shoot up quite a bit in difficulty compared to the rest of the level. While it is pretty good, it doesnt seem fitting for the difficulty of the overall level. Took me the most attempts to do in practice mode compared to the rest of the level combined, ship and ufo. The decoration is nice, although. It's super vivid and fits the rest of the level well. My only problem is seeing some of the sawblades is rather difficult and makes it frustrating because it merges in rather well with the blocks and background.

Once again, the gameplay has a nice simple feel to it. It's bug free from what ive played and is very enjoyable. The transitions are smooth from cube to robot and the use of moving objects is quite good. The decoration is pretty good as well. The use of custom backgrounds and decoration is pretty impressive, and it looks great. Everything is very well put together in this part.
86-100%
Compared to the rest of the level, this seems somewhat empty. It still looks and plays good and syncs well with the music, but the decoration overall seems bland compared to the bright and vibrant level previous. Still looks alright, though. The gameplay is very nice once again and non buggy, which rocks.
OVERALL:
Gameplay 8.5/10, smooth most of the time but with its flaws at the first ship and ufo.
Decoration: 9.5/10, appealing to the eye, simplistic yet wonderful, but with a tad missing at the end.
Sync: 9/10 Not much flaw here, it seems smooth and nice to listen to.
TOTAL: 27/30, feature worthy!
Looks great, keep it up!
