Just going to put this with all the other praise for this, "Well Done". <slow clap> I really wasn't sure what to expect when I started this adventure. After the 1st chapter, I was hooked and had to binge the whole thing. The lewd parts are nicely rendered and worked well with the story, it...
Maybe it's because, it's what I consume the most, but Ren'py is my preferred. It's easy to use and understand and it lends itself to ports to different formats easier, like for Android play.
All time favorite, so far, as there may be something mind blowing in the future would have to be Proud Father. I still go back and play that one. Just a simple straight forward and fun story.
My actual first was surprisingly, Being a DIK. I had never really seen something like it previously. The new format for sexual content was exciting. I've evolved since then, but I still visit the that first one every once in a while for updates.
Any way to get an Android port?
I actually enjoyed it when I first played it. But you're right, hadn't seen anything on it for a while, I was surprised to see this pop up.
