I’d like to know the exact causes so I can fix both bugs, although the lag issue is going to be tricky—the game runs pretty smoothly on mobile for players who meet the recommended requirements. However, we’ve tried to find ways to improve performance for players with the minimum requirements, and it seems very difficult…
That said, I think I’ll be able to fix the barrier issue without any problems.
If you can confirm both bugs, I’ll try to fix them as soon as I can. I’m really sorry for the inconvenience!
