I wanted to go into the details of what exactly went wrong with the last update (since by now it is obvious the devs made it intentionally) but then I figured I shouldn't even bother so I'll just sum it up in short: the game is no longer fun to play! All the aspects that made the fights fun and enjoyable were butchered by HP update completely.
It puzzles me how can the devs expect increased monetization if they make a game no fun to play basically for everyone and especially for new players? I think instead they'll see existing players (both free and paying) abandoning the game in droves and retention of new ones sharply declining.
That's what I did after trying the last update - I lost all the interest in the game and stopped playing (after enjoying the game for several weeks and looking forward to the next girls event).
