ok... gonna TRY and offer helpful criticism:
1) Attention span of Samantha is less than a hyperactive squirrel after 3 energy drinks. From the end of the intro text, she has about 45 (or less) seconds to get out of the room, avoid stepmother, find a place and masturbate before she gets upset and teleports back to her room. Doesn't seem to be possible, especially since stepmother usually follows her where-ever she goes.
2) If by some chance you get her to successfully START to masturbate, she exhausts her energy and cannot finish (is that even possible???). Doesn't matter if you use RMB to speed up or not - either takes too long (no speed), or she burns through the energy too fast (with speed), and varying doesn't seem to matter.
3) Both of the above being somewhat pointless as about half the time, as once she starts masturbating her stepmother will warp / teleport to her location and start yelling.
**** Suggestions:
a) do away with energy drain except in actual energy consumption acts (running, orgasm, etc.)
b) fix the stepmother where she is no longer a hummingbird! Sure, let her wander around - SOME and not always - but have her stop and do tasks / read / rest /etc. like a human being. She shouldn't be omniscient and automatically notice EVERY activity in the house (even the room she is in).
c) have a much longer time pass before Samantha gets upset and quits.
****
4) Not a complaint about the graphics themselves (not that they couldn't be better), but the model/texture in question: Samantha is ugly as roadkill. Seriously, she could walk down the street naked and everyone would look away not because of shame / nudity, but because they want to keep their lunch / dinner down. I am certain that, if the art is not your strength (which is ok), someone will be happy to assist in fixing the model/texture.
5) I am having difficulty why you would disable nudity (her taking off her underwear) in a porn game EVEN if it *is* a demo. That will lose a lot of folks right off the top (or make them upset). If you are trying to get paying supporters: this is not the way nor are you far enough along with this early alpha version (it is way too buggy). You have to show you can produce a decent product first, primarily. Then, you 'encourage' support with "supporter-only options" (NOT requirements) like optional clothing, additional locations, and additional interactions to those that are included with the free version. THIS will attract a lot more supporters.
** General suggestions:
a) Add an 'E' function for interacting with the environment. The 'sometimes there and mostly not' is confusing AND does not allow the player many options. Like the door to the closet - should be 'E' for open (instead of just running into it with her forehead) and 'E' (again) to close (which would make the first 'task' of masturabing in the rest of the house actually possible as long as stepmother doesn't somehow know what is going on through the door).
b) Use a different key to 'Sit' (perhaps 'V'?) - also using 'E' for this (like current setup) again is confusing and forces nonsensical actions (why does she sit on the floor in the corner or closet instead of standing??? Especially since the standing masturbation animations are in the game already (like outside in the side yard).
