Not really, the problem isn't technical, it's just remembering what fingering is allocated to which bar.
disregarding voicing, then the technical difficulty of this piece is comparable to fur elise.
I have one question for you: Do you play it very fast?
Left hand only --- doesn't matter. You can still practice the piece "hands separately" --- i.e. "voice separately." By this I mean dissecting the melody and other voices from the harmony within your left hand.First, though, I would block the piece together into chords and practicing playing it as chords without worrying about the moving transitions between them. This will give you a rough feel for hand shape and direction, and will establish set fingerings at regular intervals.Next, I would practice "voice separately." This is important to do regardless of what other strategies you use to go about learning this piece, because the melody needs to sing out over the rest anyway. Isolate it and focus on creating a beautiful voicing. If the melody is mostly played by the LH thumb, then one practice session might be spent placing your hand/fingers in all the appropriate note/chord positions, but then only playing the thumb voice.The same thing should be done for the inner voices --- you might find that these parts are intertwined and passed along between the melody and harmony, thus there may be more than one way to "sing" this part.
I have one answer for you: To play it very fast would be disrespectful to the piece and would make it sound horrible. Better 60 per quaver
