I agree with denis in that the first half is much weaker; I don't think the designs look too good and the structuring feels kind of rectangular for my liking. I think they could've used the slopes to their advantage by connecting blocks to each other in more interesting fashion. The ship part that follows does do this around the edges which I wish was utilized in the cube part as well. I also don't think the colors are the best here, for this kind of progression I'd imagine the first part to feel more quiet and a grayer color palette could work better for that. I think the second part does well at that.

I do like the level more as it goes on though. Especially love how the nature and city elements are integrated into the gameplay.
