Sad Ghost is the saddest ghost! Wander the afterlife in search of meaning. Can you find it all?

(Sad Ghost is a character invented by my son)

This is based on Specter Spelunker Shrinks. But instead of shrinking evenly, you can contract your width and height independant of each other. So it's sort-of like this.

Arrows: Move
Shift + Up: increase height
Shift + Down: decrease height
Shift + Right: increase width
Shift + Left: decrease width
Z: Hop

Your hop height is affected by your mass, which is roughly your height multiplied by your width.
