Has the android version been delayed or done away with?
I put a LOT of effort into keeping file sizes as small as possible, so at least for the foreseeable future android should be doable. I think there's a 1 gig hardcap and the game is only around 300mb, USUALLY going up by 5mb or less an update.
If we do eventually hit that cap and I can't figure out a way around... idk.
It takes a couple more steps but some games use a multi app install process.
You break up the game into multiple apk's which gets around the Android limit.
So you have the primary apk that launches the game but then secondary apks that are essentially patches.
No clue how complicated this is from a dev perspective but it's one of the simpler options I have seen on the user end.
