Hey Somn,
Unfortunately, there's currently no system in place for Android like that. We are looking to streamline the Android process in the future, but for now this is what the system will be.
umm to be absolutely clear, the bulk of the game is currently being loaded into RPA files such that updates require the rpa and apk both to be downloaded and installed each update. My request/ suggestion is to leave the recent stuff out of the rpa. At least until it starts hitting the limit again.
Saying that in case it was misunderstood. As to being possible or not... it is; this game is the only one that i have to download and install an rpa each and every time. I make this suggestion on every game that i play that gets to the apk limit on file size. The other part to my suggestion is usually - if you don't know how to do it, ask basically any big porter on f95 as it's pretty standard practice at this point and i don't know the back end to even try and explain how it's done
