Hi,
We have tried pricing options throughout our 5 years of releasing the game, and it's the best option for the long-run of the project and the lifetime support of the players.
The price is equals ~40 rolls in mobile gacha game like Genshin Impact. Not much you can get it 40 rolls, but you can get a big full game, with years of free content update, that has dark, buffed hunky man like Ero Condo.
