I like the artwork most of the time, but the panelling is really exceptional. The only major reason it isn’t a four star read is down to the dialogue being stilted and the pacing being really, really slow. The world building also matches the pacing, presumably for the sake of its mystery, but after almost 300 pages very little is added as to what the heck the tower actually is, among other major things. Enough fun and cool things happen that it was a good read, but it doesn’t feel like a whole lot was thought through at a macro, editorial level, which makes sense, since it’s a bindup of a webtoon.
