Alright, so this is my review.
Just note that I am not an official level judge, so feel free to ignore this if you want, as it won't change the scores of the official judges.
First key is extremely badly designed, and also very confusing.
The transition into the dual is very, VERY buggy.
Dual mode has very confusing but good gameplay.
The moving blocks aren't too bad. However, you could've made them pop up earlier to prevent more confusion.
The moving orbs frenzy is ridiculous. Even Practice Mode couldn't make me memorize what I should do and what I shouldn't.
The ship part was extremely annoying, and the second dual part could've been better.
The ball/cube dual is extremely confusing and I couldn't get past that.
Basically, I stopped at 17% in Practice Mode because of the orb confusion
Here's the overall score from what I have seen:
Gameplay: The gameplay was unique, but not very fun. 3.2/5
Decoration: Extremely bland, could've been tonnes better. 1.7/5
Originality: I appreciate you trying to make a non-effect level, but I have seen a lot of levels with decorations like this. 4.1/5
Atmosphere: Boring, there was nothing special about this level. 1.9/5
Music Sync: Not very good. I couldn't rely on the song. 1.7/5
Total score is 12.6/25 or 50.4/100.
Belongs in Decent Levels section.
