I think, a file compression is needed.
The game is now 1GB, considering the first release of ToS is already 800+MB.
What I mean is, we need a file compression since the game eats a lot of space. But there's decent amount each update, so you gotta download another 1GB.
To add on that note, an App optimization is also needed since the game sometimes lag and/or gives off slow response(Android).
That's just an opinion, no need to take it seriously I didn't mean to offend or something if you got hit by it, I just had to let you guys know what I have found
