[ti]harder[/ti]Flying Solo by me!

Cube Section (0-6%) - Gameplay is pretty decent for the beginning. Block design was pretty good too. The background however, is copy-pasted. Try variating the orientation and size of the objects, and maybe fill the area up a little more.

Cube Section (7-16%) - This part is a little plain, and I've seen the same block/deco styling in a bunch of other levels. The animated spikes could also be colored to match the other objects. Again, the area could use a little bit more filling, but the gameplay was mostly dynamic.

Ship Section (17-25%) - This area could use some work. The gameplay was pretty dull and was really easy compared to other parts. The brick background doesn't look that great and is static, maybe try brick structures occasionally instead of just one solid background. The bricks also just cut off sharply at the end, maybe try to make the transition smoother with a fade. The effect with the breaking bricks/water was pretty cool though.

Wave Section (26-41%) - The first part of the wave again has this solid background that doesn't look that great. Another problem is the block design is just white lines. The gameplay is much easier than other parts in the first part. In the second part, the blocks and background to me don't really blend together in color. Maybe try making the colors work with each other more. The squares are copy-pasted; try diversifying a little and filling up some spaces more, as well as making some more complex block designs.

UFO Section (42-50%) - The structures are copy-pasted and the background/foreground is virtually empty. Again, fill some spots up a little. The spikes don't blend with the blocks and background, try making the colors work together. Gameplay is pretty much the equivalent of Flappy Bird, try diversifying it a little. Do more things like the orbs near then end, and make the movements more dynamic.

Robot Section (51-60%) - The gameplay is better here, except for that one blind orb. The white outlines on the blocks throw off the balance of color, you should make them blend with the blocks or just make them invisible entirely. Some pulsing objects are needed as well, it's kind of plain.

Ship Section (61-69%) - The block design was a little better here. The difficult of the gameplay decreases a little here though. The main problem is the background is basically the only thing there, not to mention that it is very distracting. Much more foreground and a diversified background would be nice.

Cube Section (70-80%) - Again, the static background does not look good. The colors in the area all conflict with each other. The question marks hiding the invisible blue pads do not look good. If you need elevated pads, jut put blocks beneath/above them, instead of just making them invisible and covering it with something else. Gameplay was OK for the most part, but again, there could be more pulsing objects.

Dual Cube Section (81-87%) - The gameplay is pretty good here. Decoration is the main problem. I've said this a billion times already, but the static background doesn't look good, and the area is pretty blank. You could also add some block structures in areas that won't affect gameplay to make it look filled. Finally, the auto section. You could just make the auto part visible instead of just saying "auto" and leaving the entire area looking blank.

Cube/Robot Mixed Dual (88-100%) - The gameplay is decent, but could use a little more changes in elevation and just more happening in the middle. You could achieve this by putting some gravity portals here and there. The decoration is pretty much the same as the last part, so I'm not gonna repeat it. Cool pixel art at the end btw.

OVERALL -
Gameplay - 7/10 - Mostly good, but some parts the difficulty fluctuates and some part are just dull. Try making your gameplay dynamic.
Decoration - 6/10 - Main problems with this level is static backgrounds, empty parts, and just overall not much happening. Add some background/pulsing objects, and make some more complex block designs. I'd suggest doing more stuff like the beginning, except more diverse.
Sync - 1.7/2 - Mostly synced except for part of the wave and some other various jumps.

FINAL SCORE - 21.5/30, Decent
