There's some value here but I certainly could not appreciate it. That's not to say no one could, its not broken by any means and there is some decent content in here.
But everything just feels really generic and the aesthetic choices are awful. The first stage looks fine, but after that the color schemes become dark grey on black, dark red on slightly lighter red (see the dark area screenshot for an example of the poor aesthetics). The difficulty curve is all over the place and the avoidance bosses just felt like a drag including the first one where the final attack just instagibs you with no explanation of what's happening. You need to grab all the moons
The later needle felt like 'well, here's some generic jumps but to make it harder every landing will be 16px!'.
