Hello again
As I said, I updated the game now
Now screen tearing must be gone now, however, I'm not sure if its actually gone, since even before updating, It didn't have any screen tearing, due to the different screen sizes
I also fixed a thing where if you pressed Q in the ending, instead of returning to the main menu, it returned to the second level, but now it takes to the main menu.
Thank you for informing the bug on the game.
