This seems to be an issue with some older android devices and the current version of Ren'py my game is running on. The only solutions is updating to a later version of android and freeing some memory
I've never personally tested it, but Joiplay only works if it supports whatever version of Ren'py you're trying to run on it.
I think the version of Terrene on itch.io is running on ren'py 8.3.6, so joiplay needs to support that version.
Also, since it's basically an emulator, it will use more of your devices ram/memory. So your device needs to be able to handle it, or it'll most likely crash.
For that to happen, I'd have to remove alot of features/content, which would end up breaking the game. Right now I'm busy working on the next update and don't have a lot of time to strip it down to it's bare minimum.
All I can say, is if you have another device/more modern phone that has more ram, try using that.
