Now that's an honor!
I don't really know what's Subversive about it, it's just my way of introducing the basic single-character mechanics and then being like "but also you sort of need the different abilities of two characters." And narratively it's like, of course they wouldn't want to work together until it was necessary.
A guiding principle for the graphic and sound direction was just "what BAPuz was going for, except now it's more like a super-fancy Game Boy Color." So basically every sprite has only 3 or 4 colors, and some palettes are shared by a number of sprites, though it definitely breaks the rules in places. (The fade transition and level select previews even use alpha channels, which is shameful, but the latter especially needs it.) And I didn't rip any sounds from Tetris Plus this time!
