I like that you went for a style and it carried through with a lot of the theming. I do think it's a bit tough to make games that require a lot of flow and level design. Speaking from experience, these games are much harder then they appear.
These games look pretty simple on the surface due to not seeming like they have a lot of mechanics. But the mechanics are usually tuned pretty hard and the level design is tight.
I think at the moment, it's a bit hard to go through the levels quickly. I found it hard to maintain speed consistently due to hitting a lot of walls and spikes. Sometimes I am able to break through a lot of blocks without slowing down. Other times I get stopped and I am forced to stop.
I also think the camera is too zoomed in too see what is going up ahead compared to your speed.
Still I think this is not a bad attempt and I see the vision you are going for! A bit more time to polish up level design and physics would be all it needs.
