Well, I'm not gonna lie, I did find the fanservicey bits kind of uncomfortable, but I recognize the cultural differences inherent in the design philosophy of a game like this.
It's irritating to me from my perspective, because the game and cute characters can stand on their own without needing to get all creepy, but having gamed through the 90s I simply can't support obliterating a product to make it more culturally acceptable for certain markets or demographics.
Basically, the one game in the series I've played is Meruru, and I thought the game would have worked no matter the kind of cute characters included. If the game had been full of cats it would have been still been fun and cute without needing the creepy bits, but since they know their demographic, they went with little girls in skirts.
