Playing on the full game APK, made it past the mission that was bugged and got to the quest when you meet emiko for the first time and help her out, so far so good except a few missing backgrounds still but no freezes or game breaking bugs
PS: I still think its a better idea to have a full version and a launcher version for the PC version as well (edit: If you do end up adding the launcher to PC which from my understanding you will add it) just to avoid any issues again and personally downloading on my phone via Itch was faster than downloading via launcher
