I think its more a scam for the money, i mean a quick look at her Patreon and your greeted with this
"$1,017 of $2,500 per update (untill release of update) "
There is only so many ways to take that, she wants 2.5K to update her game? Really?
You misread that. The amount which she currently has in pledges is $1,017. The pledges bill per update (until the release of the next update), meaning that she isn't making any money at all until she posts a new update. After she posts a new update, she will revert to the previous billing model of monthly billing for pledges. This has already been discussed at length in this thread.
If you had read more carefully, you would have seen that the place where she says "$1,017 of $2,500" is where she shows her benchmark goals. This is a common thing on Patreon. Users will set a goal, show how close they are to the goal, and then explain what happens when they hit the goal. In this case, once she hits $2,500 in pledges, she says that she will upgrade her video card and devote all of her time to working on the game.
So the points you raised in your post do not in any way make it more likely that she was running a scam.
Not that that helps, since we're unlikely to ever see another update to this game.
