Good; you may still try my review, else see (although mostly scornful and rich in spoilers) opinion in English.

His rating could have went higher had he, like me, read it as a parallax novel. Between Hardboiled Wonderland and The End of the World and this work, to me, does exist approximately the same relation as between Orson Scott Card’s Ender’s Game and Ender’s Shadow, or, better, between K. W. Jeter's Dr Adder and Death Arms. The former of Jeter’s novels, of course, is stronger, being in fact the unrecognized cyberpunk LUCA, the latter complements it in another slice of stacked realities, close but different in some aspects. It has its own reason to be read, though, sure, not up to the mark of the genre-defining books.
