I hope the text sex is just a placeholder until dev can add cut-ins.
Honestly, I feel this is the big thing right now that will make the difference between this game being the next Karryn's Prison level of great, or fall into just another Malaise and the Machine "nice art but going nowhere until abandoned".
Right now, the most important thing is to flesh out what you have, add these cut-ins, add the facial expressions so they match what is occuring, whether it is by cutins or just having the standing sprite change this is the thing at the moment that makes it feel so much like a placeholder demo and not a full game teaser.
Don't get bogged down with adding anything new which is requested like clothing/body types/futanari/pregnant content/additional poses UNTIL you have added the visual aspect and fully covered what you have now while fixing any combat loops. That will show a full and complete game foundation and you will have the hype and support going forward.
