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.

Neat! I'd like to see this
Neat! I'd like to see this idea fleshed out more.
I really enjoyed growing horizontally to bridge that one gap, rather than attempting an impossible jump. I also like that you can just make yourself really tall to skip the whole right tower.
