Dude I LOVE your games, they're not "simple adult games" they're shocking with a lore behind it. (sorry tho I didn't play the first game)
About The Gameplay;
In my opinion winning/losing a round should be faster, It was too slow for me at one point I was scared that I'd quit the game without learning the remaining lore. Also I didn't really understand why you only used 7+ cards for gameplay, it was kinda annoying sorry. But the rest was good, the art was very very mesmerizing.
! SPOILER AHEAD !
About The Game; This game gave me a thrill that I wasn't really expecting, I was getting uncomfortable with each win I get. But getting more excited to learn the lore behind the game. I was pretty much scared of BlackJack's dedication, the most heartbreaking part was the Jackeline. The way she knew she was gonna lose and it wasn't about pride but life. The way she still kept loving BlackJack even though he killed her slowly... But still after her death, BlackJack kept her. His light on his eyes went dark, he was now working only to bring her and not to win. He even refused to fix himself just to revive her. The lore is too deep and I love it, I'll just wait for the updates for now since I finished the game on a single sit!
