It's not really feasible to spend the game dev time to figure out how to do that, i've already tried to optimise it a billion times, the Android version is just straight up not reccomended. The optimal way to play the game is on a windows computer.
The game is currently 1.5 gb on android and it's only going to get bigger, so yeah you're right if your device can't handle a game with lots of video files then I would pass until you can get your hands on a laptop or something. I appreciate people giving the game a shot though.
