Concentration: How about an Easy Demon 10
with a bossfight level, kind of similar to Xender game, but to "kill" the bossfight, you need to try to decommission it with the usage of switches or zaps. This will be a series instead, so there are multiple bossfights. Each level will be set on a planet of a “solar system”. Each bossfight will try to destroy the planet because they’re known as “The Destroyer of Systems”.
Brainstorming: “Something that would be cool is a level in which you go through the rings of a planet in the rings. Within these rings, you'll dodge some asteroids and rocks that make up said rings. However, an interterrestrial entity from another star system has also entered and wants to battle. You must battle and defeat it to save this planet.” (MechaBrain)
SCAMPER: Using Deadlocked as an example, see that one bossfight in there? What if I made Deadlocked, but instead of the good old RobTop style, I add in tech and astronomy. I could make Deadlocked like some Xender Style level and implement some new mechanics.
Ramsey Method: (https://en.wikipedia.org/wiki/Star) I can add Messiers (Like the Seven Sisters), constellations, and possibly a telescope. Maybe at the end, once you beat the boss, the boss will become unstable and will explode. If it does, the planet dies, so in order to save the planet, you need to teleport the boss into a black hole. This whole part will be a cutscene.
