Whenever I boot up the game on Android, it just crashes, It either shows the godot engine logo or just a black screen then boom, it crashes.

Im guessing the android versions aren't for low end devices, will there be a low end version for the android port soon?

The game generally takes around 30+ seconds to boot, since it loads everything up on boot time so the game is played smoothly afterward. A custom version for lower-end devices might be impossible unless we cut a lot of content like hairs and stuff.
