Thank you very much, BossDragon. I'm glad you like the game and that the graphics evoke pleasant emotions! Yes, initially the graphics are made in 3D (in Blender), I model, texture, animate, and then render into frames. And then it ends up in the game in this 2D form. This has its advantages—you can use all of Blender's capabilities to achieve the desired look, but unfortunately, it also has its disadvantages—limits on the number and size of frames in animations, problems with customizing the appearance of characters/objects, their interaction, etc. In addition, this game engine, which I am somewhat familiar with, does not support proper 3D at all.
More sex scenes will be added gradually as I work on the game, and the next small update (in the spring) will be dedicated to this ;)
