For the rollback:
When it comes to choices, it does work, but when it comes to using it in the Casino it will be used even if you try to save it in a different file.
I had 11 Wishes and tried to use it with the "Medium" chess difficulty ,but saved my progress before I start the match.
After I lost, I went back to my old save and I only got 1 left.
Also, I don't think Chess is a great minigame here not because I'm not a fan of it, but because it kind of look lazy at least from my perspective. Since it's also a "Casino", it would be better if you stick the theme of the game with the place.
About a "bug" that I found, in which I'm not sure if it is:
In the shopping mall, the green vibrator closest to the screen and the pink vibrator on the right shelf can't be clicked/bought.
Mhh...that's interesting because there isn't any wish subtraction in the casino. So you should never loose wishes - the only expection is, using them in the chapel for gatcha. I will take a closer look and see how the behaviour could have occured.
I will update the chess minigame visual, no worries. The current state is there to give the player some variety for build endgame grinds. Since I didn't wanted to subject the player to playing the rythm game over and over again.
Is on purpose for this version!
Thank you for telling me all of this.
