Heads up, the cheating between the girls stuff shouldn't have been added imo, the dev doesn't want to make a harem game that much is clear. But adding cheating routes into bad endings is not a good sign that I can comfortably continue supporting.
Sure, I think it's completely fair to have these opinions, even if I think you're being a bit more extreme about what's actually happening. And you do vote with your money. I haven't supported the game in three years for my own reasons.
As for your previous message, what do you mean by "vanilla"? The cliffhangers have been a thing since Yasuka, but I do agree they've gotten worse over time. Asami's kidnapping is probably the biggest offender, considering that's been hanging over us since what, v0.8? It's getting a bit silly now. 😅
As for the leaking, RNGeusEX was already saying something like 93% of the game was being obtained illegally three years ago, well before any of the bad ending stuff was announced, so I'm not sure the bad endings are really going to drive much more leaking.
