Hello Emily! Thank you for pointing this out. I did a double check and I believe there is no issue : under the NoDerivatives license you may use the asset as long as you do not transform the material itself (eg. you may not change her hair color, clothes, etc). It is fine to use the asset to make video games as long as you use it as it is :)
I see, thanks for clarifying.
Hi! I want to use your work for my thesis project (non-commercial), but the ND prevents me from making small changes necessary for it to fit. Can you consider chang it it to allow derivates with mixing the features of your art? I basically would want to states that have neutral expression, but open and smile mouth, using them from the other expressions.
