Saw the update; great job. Some were difficult and some were easy. I hope you make your game into something you want.
By the way, I wonder if you make a strip rock paper scissor game between two girls; if one loses, it will end with the loser posing, but if both end naked in a tie, it leads to attraction and lesbian sex, leading to the true ending. Will you be interested in that?
I hope so=)
About your idea. Drawing lesbian sex is harder for me than creating a rock-paper-scissors game. And the first is more interesting without the second than the second is without the first.
First, I'm going to add scenes with handjob, blowjob and titsjob. Only after that I will add the second girl.
Saying that drawing lesbian sex is hard, I see. I would offer some links showing the lesbian reference if it's okay, and although I am confused saying that you would do the rock paper scissors but cannot do lesbian sex because it's difficult, perhaps maybe you can do the strip rock paper scissors with both girls but maybe include the lesbian embrace for a secret ending for a start, I think.
Anyway, looking forward to the next update in the block saga that involves sex things, like the handjob, for example, including the 2nd girl, and hope you make the strip rock paper scissors someday but with two girls in it.
