Thanks for checking us out. For now its going to stay 3d. But depending on the game engine and the platforms we release it on it may vary. But 3d right now. Mobile platforms will have more 2d sprites for example but its always easier for us to go down rather than up with our tech.
Hey, great! And those meshes do not seem as high-poly at all! You will see in profiling scenarios that it is (much) more performant to have more verticies than large detail textures for wheather normals or color. Keep up the good direction :)
