Sure, no problem. Just let him know how to turn on the sprites using ACL. And if you could ask him what MU in the model number stands for. I'm thinking maybe because it's a "Made Up" game ;-)
New reply from Florent Gorges :
Well, MU-21 is a private joke with my wife ^^
In Japanese, MU-21 can be readed "Munii". And Munii is the favorite rabbit puppet of my wife (when she was a child)
that's all ^^
one detail, the book and illustration copyright is not Pix'n Love anymore. It's "Omake Books Publishing"
