One question how did you get the game small enough to send because I worked with Unreal Engine before and the game file became too big

All the textures are 128p, 256p or 512p. All the models have less than 800 vertices. For example, the fox mesh has two texture maps, one for his head and one for his body. Both of them are 256p. The body texture is only 8kb because it's fully opaque. The head texture needed an alpha channel for the whiskers. So it's around 16kb. I think the Engine part of the packaged game only takes like 200mb of space.
