I think 80s/90s edutainment is what she's shooting for but shit that was exciting in 1980 is not going to be exciting to kids now in 2016.
This let you go "whee I'm playing a video game!" and it motivated kids to do math for hours on their own. Now days internet advertisements sometimes have better gameplay.
It's supposed to be mathblaster with a female protagonist so that girls can play the game, learn math, and get early exposure to a female engineer. It's not a bad idea, I just doubt the game is engaging enough to make little girls wanna play it on their own. The hard part of a kids edutainment game is making it fun... this has been the challenge since forever.
If brianna had bothered to notice most popular apps are re-hashes of very old games (angry birds, flappy bird) and went here:

Played them until she found one that was engaging and easy to code (lots of this was written by one person in basic in their spare time), and then made the protagonist a female engineer or other role model. she could have made a game as a community college project for guidance instead of hiring programmers and easily broke even and used the experience to crap out a series of ever more complicated games, each turning a small profit and then built a brand making fun educational games for girls.
For a lot less than 400k.
Actually I'm going to do this now.
