Depending on how large of a game you’re creating, can make the size of the package larger than usual. I would suggest blacklisting or removing any files that you’re absolutely not going to need or use in the project. Secondly, I would make sure that the cooker is compressing all cooked files for the package.
This documentation is directed towards Android, but there are some useful tips: [Reducing APK Size][1]
Let me know if you’re able to get the size of the package down or not.
Thanks!
