Looks pretty cool! Let's go into the details now.
Design/Decoration: Nice, decent design. I know you tried to aim for a simple look. Don't get me wrong, simple levels are great, but my opinion is that you have made it a little
too simple. In many simple levels, the amazing block design makes up for the lack of custom background. But in this case, the block design seems a little underdecorated and the custom background does not make up for that. Also, for the moving objects, you could've added a noticeable easing to it, because the portals and orbs that were moving didn't look very good because there wasn't any easing. Another thing: you carried out each custom BG or block design for a long time. I feel you could've changed the block design and background every 1-3 gamemode changes. That would make it look much better. Other than that, it looks good
I'd give it maybe a 3.5/10 in design.
Gameplay: No problems here. The gameplay was not at all boring, it was somewhat fun and interesting
It was not a really exciting gameplay though. An exciting gameplay is when, if you die anywhere, you won't be raged or anything, because you get to play through the whole level again and experience the fun again. However, only some levels have exciting gameplay, so it's not a huge problem
I'd say it's a 6.5/10.
Music Sync: Music sync was pretty good in this level! No off-timings or anything, it's not bad
Again, I don't have many problems here, except for the fact that you ended the level with the drop. Usually a drop happens at around 40% in a level, but in this, the drop happens at 100%... pretty weird :/ I'd give it a 7/10
Originality: Not too bad, although the 'simple' style is pretty overused in many levels. I've seen many such levels with the same style, and some look exactly like this. I'd give a 1.5/10.
Overall good level, with a finishing score of 18.5/40. I guess I could cut you some slack since this was made in 2.0, and in 2.1, you could've made it better
(P.S. I'm not an official level judge, but I wanna be one, so could anyone review my review and see if I qualify to judge levels? Thanks
