Hi! Android files are larger because they include all assets and device support in the .apk directly, while the Windows download is compressed. Once installed, the actual game size is similar, and the size of the game is mostly images, more than 500 1920x1080 images basically
Yeah, that's actually smaller than an uncompressed Windows Build because Windows uses full resolution for images while Android has more compression, windows size is closer to 1.4GB
