I bought both this Neoplasma 1 and have been playing the 128k version on my Next (switching over to TRD so I can persist saves!)
The game is incredibly addictive and polished - I've stayed up for hours playing it when I should know better.
The art direction is also stunning - I actually prefer the 128k version but I miss the 2xAY tunes.
I look forward to whatever you do next.
