-Updated a hint sign to make it more clear that restarting levels is sometimes required

-Updated a splash screen

-Changed the fullscreen input on Linux to Alt+Enter, so that it's consistent with Windows

-Fixed a bug where hints would sometimes appear for the wrong character

-Adjusted the positioning of text on the top part of the HUD

-Tried to optimize the game a bit more
