Sorry for replying so late ðŸ˜,because itch does't notify me at all.
Most of people don't meet this situation and run it without any problems. I think this problem maybe come from your old Android version (Android 13 or newer recommended) or your phone security application.
I am so sorry for can't return your purchase because It's been too long time, but we have PC and Mac version, I hope you can enjoy it on other devices😊
