Okay, had a chance to give it a go and here are my thoughts...
It is pretty short for a demo, I sort of made that mistake when releasing my own a few months ago... it is understandable that you want to get something out as soon as possible to try and start earning some money, but be aware that you are going to have a harder climb in getting support, as most people will now choose to wait a couple of months to see how far you progressed before donating.
My suggestion is be responsive as you have been to the members and provide regular updates, keep them informed and they will come to support you.
Another thing I'd suggest is going with something like Mega.nz to help distribute your game instead of Google, as you already exceeded your download limits for the day and anyone looking to try it either have to wait 24 hours or play it online, which many won't do out of fear of Malware, Trackers and such... and there are no download limits with Mega.
As for the game itself...
It is interesting and wish we'd get a little bit more of the story.
I know that what you animated isn't easy and it is done very well, though remember the positioning of your assets... for example, when she is having sex on the bedroll, the male's penis isn't technically in her... and it is noticeable to those that are going to want to fap to this.
The blowjob scene is done really nice!
On a personal note, I'd have preferred her to be a bit more bashful in the fact that one will take her top and the other will take all of her clothes... perhaps if her top is taken, she will walk around covering her chest or if all of her clothes are taken that she walks around with her arm covering her breasts and a hand covering her genitals to try and hide her nakedness...
...build up to her being an exhibitionist for the players, it will give you more options in your story such as concerns about being seen... wanting to hide, being embarrassed and slowly being to turned on by being exposed and nude in public.
I get this is just a demo and showing people the sort of "action" they can expect, but if you are going to express and impress on them there is an in-depth story, set that first and foremost and hook them with the story... it will make them hungry for more and generate you more of a following.
Please, please, please don't think that I am being hard on you... I like what I saw and think that this is very unique and, if done right, will bring you a lot of support. My interest is seeing you succeed in this, as it is something that many haven't done or tried, so there is certainly a niche for you... with a little more polish and elbow grease, this can be a really great title!
Keep up the great work, don't get disappointed and keep at it!!
