Some users in the Steam forums and even on Twitter have brought up the fact that the recent addition of the model viewer to BLUE REFLECTION’s dressing room in Western version is not the same as the one found in the Japanese release. In the Japanese release you were able to rotate the girls vertically so you could see their undergarments, and this seems to have been removed from all Western versions of the game.
The below footage is from the Japanese version of the game.
This video shows the Western version of the model viewer in action.
The model viewer mode was not added until the 1.05 patch in the Japanese version, but was never hindered in this way. I have reached out to Koei Tecmo for comment, but certainly hope that this is not a case of them making a change to the game’s features without letting customers know before the game was released.
Thanks to @Sephi24 for the tip.
