No one's reported that yet, but I'm not sure how many android users tried it. Since there's mention of a 2GB limit (and this does go past that) it might be that some configurations can't recognize an apk of this size.
I'll let you know if anyone reports a similar issue.
This might be a problem then and I'm not sure how I would fix it. The game is over 2GB and it's only gonna get bigger, so if it's because of that, well... I don't know what to do. I'll ask around
Okay, I further compressed the game to a smaller size for the APK (hopefully without noticeable quality loss for smaller screens). It should be able to work now. Let me know if there's still a problem.
Also, if you have saves from a previous chapter, let me know if those are working or not.
