Cube Section (0-15%) - The block design is pretty good, but the background needs a little bit a filling, and the white kind of conflicted with the purple. Also the custom background doesn't look that great. One of the blue orbs was kind of awkwardly placed, but for the most part the gameplay was OK. The transition into the ship section is empty, try adding something to look at or add gameplay to it instead of just leaving it blank.
Ship Section (16-30%) - Again the block design was OK, but the blocks used look a little outdated. I would also suggest making some of the decoration Light-BG or blended. The custom background needs a little work, it's the same dirt blocks copied over and over. The gameplay was OK, but some parts you could just run into the obstacles without any punishment.
UFO Section (31-46%) - The custom back again could use a little work, it's mostly static and almost looks a little glitchy. The decoration used was the same arrows and stuff, maybe try using some different stuff. The gameplay was a little bit dull, maybe try making it a little more dynamic and more diverse obstacles.
Wave Section (48-56%) - The custom background is really not good. It's super distracting and takes the players away from the gameplay, and is copy pasted over and over. Also again the white really contrasts with the green, and some of the deco pops out too much (try using light-BG or blending.) The gameplay was decent, but again they could be a few more obstacles in between; there's a few gaps. And again the transition to the next part is empty.
Cube Section (58-75%) - The transition into this section is kind of sudden, there should be a little more time to react. The decoration is identical to the rest of the level again. The gameplay was pretty good, not too many orbs, but not too little either.
Ball/Ship Section (78-100%) - The platforms for the ball section look out of place; try connecting them to the ground/ceiling and maybe making them look a little better. The ship part is pretty much exactly the same as previous ships, with a few more gravity portals. The gameplay was more dybamic than the rest due to the gravity portals, so that's good.
OVERALL:
Gameplay - 6.5/10 - Pretty good for the most part. Good usages of orbs and gravity portals. Just try to make it a little more dynamic and exciting, give the player a little bit more reaction time for some parts, and overall add a few more obstacles.
Decoration - 6/10 - The decoration wasn't that great. Some parts were empty, some parts needed blending, and all of the decoration is exactly the same throughout the whole level. The custom backgrounds were plain and some were way too distracting. and some of your color combinatyions didn't seem to work with each other. On the bright side, your block design is on spot. Just try to pretty up your level and make the decoration varied and smooth flowing.
Sync - 1.7/2 - The UFO and wave weren't really synced, but the rest was spot on.
FINAL SCORE -
21/30, Decent
