How to reduce the size of unreal engine4 game

I have create a fix screen small puzzle game. In which I just have created yet 50 level. I have to create near about 200 level. The problem is that the game size now 300 mb. Still i have o create 150 level. That also will increase it size. So how can i reduce the size of my game.

300 mb is nothing.

A game I just made installs at 8GB, and that’s still small by today’s standards.

One thing though, in the packaging settings, make sure you list the maps you want packed. Otherwise the system will pack ALL maps in your project folder hierarchy!
