Deimos - hard demon megacollab (+YT)

Gameplay (11.1/20)
The beginning isn't that fun. Not only are there invisible portals, but everything is tinted blue and hard to distinguish. You could remove the tinting to improve gameplay. Some of the base gameplay is pretty good, but the portals and orbs mess things up. It gets better after 22% because then the gameplay gets a lot better. However, some fakes are apparent in the level. However, then there is a kinda spammy wave part with invisible portals that should be removed. The gameplay itself need less wave spam.

The gameplay gets a lot better after that wave part. However, the weird portals reappear later on, and also are accompanied by a weird robot part where you actually have to jump when it looks like you don't have to. It is just weird and could have been improved. Then, the later parts have a slew of tinted portals which should be fixed, as well as invisible portals which should be made visible. Then there is that wave part...god....no....it is the memory part from A Bizarre Phantasm.
Design (5.4/20)
The block designs are pretty good at the beginning, although the decoration is a little bare. There could have been more decorations. The next part isn't as good because the light blue and dark blue don't really work so well together color-wise. The next part is also kinda poor because the decorations are bare, and the colors are weird. At least designs are good later on. Overall, the level is just too empty. This applies for many of the parts until around halfway through. Then the level looks a little better because there is enough decoration, but the colors could still use some work.

The part after that could have had more blending, to work better. The part after is bad, because the background is unoriginal and lasts for way too long. The designs also could have been better in some parts, as many blocks are just a solid black block. The intermediate wave part is better, but is kinda unoriginal and has a bad transition into it. You could have made it start as black. Also, in the wave key part, the black decoration could be removed or have the color changed as it doesn't overlay with the background well.
Sync (6.2/10)
Most of the earlier parts are a little off. However, background pulses do appear later on and improve sync. A few of the early parts have good sync, but several do not. The parts around 40% are also off-sync transition wise, but later on they get better. The part with the unoriginal background is pretty well synced, until you get to the key wave which has minimal, if any, sync.
Originality (0.9x)
This level is not that original. There is the background 55-63% and 72-96% which are just not original. There is also the effect in 63-72% which isn't that original either. Plus you used the unoriginal effect for a while in the level.
Total (20.4)
Decent.
Difficulty
