A lot of very nice melodies and psychedelic sounds in this album!
However, some of the key changes and melodies just seem out of place or arbitrary to me. I'm listening to P.S.Y. Love You right now, and its got your standard psy bassline & kick drum, and layered on top of this are some swirling, rhythmic, psychedelic sounds, but no musically tonal or melodic elements. Yet the bassline key is shifting. To me, this doesn't make sense. A key change only is musical to my ear if a scale and tonic key has been established and identified (with other melodic elements). Without this crucial information, my brain gets all tied in a knot when there's a key change, because I don't know if we're going from tonic to dominant or subdominant to tonic, etc.
I'm fine with non-melodic psy, it's just that the bassline key needs to stay constant, or only stray from the root key for short periods of time.
However, overall I applaud Psykovsky's effort and experimental bravery. 8/10, I'd say.
