Interesting concept.
Unfortunately I think it's more tedious than enjoyable. Once you figure out how staircasing works you have pretty much seen all the concepts. Also I don't think the power mechanic adds too much to it. It is more of an annoyance that punishes small mistakes in execution.
The further rooms made exhale slowly the moment I saw what the objective was but knew that executing the solution would take ages.
Art-wise this is great and I enjoyed the music and atmosphere very much.
