The asset pack looks fine to me, but the game page can be confusing. Here are my suggestions:
1. Remove the reference to 2.5D while keeping the reference to overhead (ie, top-down). The asset pack isn't really 2.5D. 2.5D is when you take a 2D game, and add 3D models, and possibly 3D real-time engine lighting or real-time shaders, and it looks part 2D and part 3D, but is really 2D. Just my 2c.
2. I'd specify on the game page the allowed use cases for those purchasing the asset pack. Such as whether the asset pack can be used commercially, whether it can be edited or not, etc.
