If your goal is to reduce the “Download Size” value from your applications Store Front then yes, Easy GooglePAD can reduce that number! I myself have managed to get it as low as 45mb~
Without delving to deep into details and options and all that stuff,
There is 3 Asset Pack options when using GooglePAD, install-time and fast-follow, which both adds to the “Download Size” text displayed on your apps store front, and then there is on-demand, which does NOT add to the store front app size text.
With on-demand you still have to download the content once the application has booted up, the nice thing is that you can decide to do it all at once (With flashly graphics in the background from the game) OR as needed, the download can run in the background while the player is running around in a tutorial level or while they are navigating the main menu, the choice is completely yours.
TL;DR: YES! By using GooglePADs on-demand asset pack feature you can reduce the initial download size from play store.
Hope that answered your question!
