Sounds were added in 0.1 and have never been updated since then, so yeah...
As for the stream part, the grind is heavy and I dont think its skill issue since you're hindered by the number of requests you get and to raisn the access level you need to fulfill them - it's not confirmed but I have a hunch that dev deliberately made it that long as a preparation for future updates or new items locked behind certain access levels (such as upcoming condoms will be available if you reach silver tier)
The x-ray - it has already been updated, though it's a simple animation that plays whenever mc cums inside of her, the game isn't ready for multiple creampies yet, but there are plans for that feature to be added eventually
