One person asked on his patreon why the new game was not released but no answer yet (he almost never answer there). Anyway with new 2.06 version, the save is no longer compatible (you have to redo all the game), and after unlocking everything one after another you clearly see the progression of the game : the female character is almost not the same on the first gallery pic compared to later and for the ingame animation, some almost appear censored for the breast (no nipple/not seeing the breast on most of the midgame animation). Also the last animation are clearly from Fighting girl sakura R.
It's a shame as the art was really good in the previous game, they could have improved the gameplay or the existing art, and I am sure it would have been better.
Let's cross fingers for the next game.
