Great little twist on the first-person puzzle genre. I particularly loved the revelation that scale itself was a kind of resource - having to drain scale out of a bigger or smaller object to be able to transfer it into the others was really interesting, especially with how it worked in both directions - shrinking something to make something else bigger, or embiggening something to have enough "shrink fuel" to shrink a cube and post it through a slot in the wall. Really smart!
