Hello there,
having an opinion is ok, calling something that someone worked for shit just because you dont like it is just rude. Many people like the new look, is it unanimous? No, but nothing ever is most of the time.
In regards to the second statement, many people also enjoy the minigames, this is not a slideshow to view nsfw images nor is a simple visual novel. As to why... really simple, Kal wanted to increase the quality of the minigames, and so he did.
