As a fan of maidcore musics, I really look forward to this game.
Sadly, I'm not a native English speaker nor Russian, plus bugs mentioned by other comments, I usually got confused while playing. It feels worse when I cannot find a backlog function to help me go over again.
However, I still love this game. It is like Va11-hall-a but with more explorations. I'm willing to get to know every maid in the game, and the whole world setting is fascinating, too.
Anyway, the game is fairly a good visual novel adventure game. I believe a success is waiting ahead as long as the full game gets rid of tons of bugs.
