Can anyone transcribe a piano solo piece to "The Melody of Logic must be played truthfully"

This piece is very nice. The chords and the melodies are not hard to transcribe (i say that because i tried and had them written down ages ago), but i am not sure how it can be arranged into a piano solo... anyone any ideas?

Edit: by the way the original title is 推理の旋律は必ず真実を奏でる (suiri no senritsu wa kanarazu shinjitsu wo kanaderu), which should translate to something like "the melody of logic definitely plays the truth" (or the melody of logic always plays out the truth).
