-The following changes have been made to the game. 1. changed the setting so that the cursor does not leave the window after the game starts. 　When opening another window during the game, use Alt+Tab to switch windows. 　To exit the game, click the Exit button in the title or press X in the window while using Alt+tab to switch windows. 　Because the cursor was not visible, there was a problem with unintentionally pressing the X on the window, causing it to exit. 2.Larger click notations in the options during the game. 　Problem with left-clicking the 'Close Options' button when returning in options during the game, which also causes sushi to drop. Right-click the button or use the ESC key to go back. 　 　I wish I could close the option and drop it after a bit, but it's not working a bit, so please keep it that way until it's resolved. 3.Other minor fixes 　Fixed that the frame did not appear when the cursor was hovered over the end button of the title. 　Fixed that the font of your rank in the ranking was not changed. -Future updates planned. 1. addition of rare characters 2. adding a function to turn off the result screen and make the board visible during checkout. -Defects. 1.Suspicion judgement. 　The same sushi is in contact with the same sushi but does not change. 2. disappearing material 　The moment the dropped sushi hits the same type of sushi, it disappears. 3.Score Ranking does not load 　I have confirmed that the score ranking does not load for some people. 　I would like to update 1 and 2 as soon as the problem can be resolved. Regarding 3, we believe it may be a Steam setting, but at the moment the cause is unknown. The transmission itself seems to be working, so please check in Steam's Community Hub -> View Data -> Global Ranking. -Specification. When the sushi is large and sometimes generated, it contains smaller sushi and shakes pulls, but it is a specification. Liveness. -Under consideration 1. Steam achievements 2. time attack mode (5 or 10 minutes)
