Thanks for your high praise!
We did not want to disregard the black/white theme outright so we used it to our advantage by highlighting important things using colors. Not the most inventive use of the theme, but a legitimate use.
Because "point navigation" only allows for a finite set of states and there not being uncertainty in the system, I think the game definetly classifies as a puzzle and not a strategy game. If Tetris is a puzzle game, this game wants to be one too :)
