Concentration: A level where you're on a dense forest that starts to deteriorate as you travel through it
Brainstorm: A level based of "Outer Wilds" where you explore diferent planets
SCAMPER: A level that consists of Deadlocked but making each part of the level appear at random until all of them have passed (for example, you could start in the "I like this part section" and end at the first wave)
Ramsey Method: Stars are more blue the higher the temperature on it's surface, so and idea for a level could be having diferent sections with stars in the background with the harder sections having stars with a blue tone and the easier ones with a orange tone to relate the "heat" of the surface with the intensity of the part.

In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines. Each line indicates a particular chemical element o...
