Thank you for your feedback. I will fix the issue related to the mobile platform. In fact, I also encountered this problem during my own testing, but since it did not affect the game process, I haven't fixed it yet. As for the shrinking mechanism, initially my game allowed players to choose to either enlarge or shrink at will. But later, I realized that the shrinking mechanism was extremely useful because it would reduce the size of the character's collision area, making it easier for the character to pass through various terrains. Therefore, I later added a limit on the number of shrinking attempts, which might have led to it being overlooked.
