It's resource management/puzzle where you loose the keyboard keys you bound each level so you want to use the fewest keys possible to accomplish the necessary actions.
Basically you want to bind all the keys first run so you can explore the playfield and actually see what's there, then reset and plot your path for maximum efficiency. Neat. Definitely the seed of an interesting game, really drives home a theme of "loss of control" (which is not "out of control" necessarily but close enough for sure).
