Too big size of simple 2d project

I made simple 2D project with few levels. Its content size folder in UE 70mb.
But than it deploying (windows 64bit) its became 386mb

  • 229mb “Name of project” folder
  • 103mb “Engine” folder

This is OK for simple unreal 2d project? How i could reduce size of full project to 70-100mb?
