# Experience
- Adjust the background image and transparency of the pickup hint window to avoid excessive blocking of the screen.
- Adjust the position of the curse hint to avoid overlapping with the room clear hint.
- Adjust the item switching UI to avoid the problem that some text cannot be read clearly on small screens with low resolution.
# Bug Fixes

# Localization
- Adjusted the Japanese translation of the text that was incorrectly translated as "薙刀".
