Subject, Skills, and Grade Level
Gravity & Physics; Applied Spatial Reasoning; It teaches how to manuer and think about movement in space and grounded settings. Think of this as applied physics learning in the form of a TTRPG. Middle to High Schoolders and up might have the most fun with this.

Time & Players
Honestly? Not sure, that's up to the GM. It is very group friendly but in turns. It scales from small group to an entire class by running it turned-based or puzzle style. Such as you have.... 5 mins to plot your way hrough this, give a coordinate path.

Rules, Tools, & Assessment
It's my standalone minisystem, so it can be slotted into anything. It can also be played GM-less as a series of puzzles; think of it as an escape room. The teacher can make a whole space station with specific modules using this and have students navigating thoughou turn-based. To play all you need is logic, reasoning and to make a layout for a small to large space station. You can also use it to make a HALO ring type of thing with gravity flux (if the core dis damaged) by inegating a place where 1 is the grounded and 0 is the vacuum of space.
