You've probably already seen all the sexual content this version has to offer. More scenes are coming soon for the current cast of characters as well as a couple of new ones a little later into the future. I plan to steadily add a few new sexual encounters to the game with every major update.
You'll have an easier time figuring out what you've done wrong in Sphinx puzzles in the coming patch. The game will list the changes done to each tile, so you'll be able to count exactly how many candles you've lit or which pillars are activated without revisiting all the previous locations.
I'll keep an eye on how much trouble players are having with my puzzles. They're a large part of all of the games I made so far, but I understand that unlike a more physical or tactical challenge, they can become very frustrating if they just don't click with the player. Hint systems for cases where puzzles bar game progress are probably a must.
