I think 0.3 should be more stable, you may want to wait for it to be free here at itch or join patreon and try it, can't promise it would work though but it should work in most androids (10~15 or more)
Hum I'm so sorry, I think I can cancel your subscription if you want.
I think patreon gives the money back, don't hesitate to tell me
This is an answer I gave to an user with the same problem at patreon. (perhaps it was you? the name tag is kinda different):
I'm currently checking possible optimizations on my side, but the issue is most likely related to hardware limitations: Unreal Engine games seems to need way more RAM than I expected even though I'm using stylized graphics... If possible, please try closing background apps or restarting the device, as this can sometimes help with available memory, but can't promise it would work.
