I srsly love this, from what I saw I think there's no possible way to softlock yourself which is rly satisfying 2 me.
I think a simpler way of saying that is that being able to keep a box with stuff in it is pointless when I can just have a bamboo with bamboo in it to spit out, plus the ability to transform that spat-out bamboo into whatever is needed by transforming the spitter bamboo with wand, using the transformed wand to fulfill the need, reversing that transformation so it goes back into being bamboo ... ok nvm not simpler
the ability to create a bamboo chain next to a wand allows you to create a wand chain by turning the bamboo into wands. using wand chain to transform wands into a bamboo followed by a rotater allows for a branching bamboo--> wand chain. with this you can take the wand everywhere. ALL levels that start with a useful wand can be won with this technique. Any level using a wand that does not focus on preventing this technique has Cheese. of the three below, this includes the first one.
