I faced some significant input lag when trying to play this game out of the box. However, adding the aforementioned launch option fixed this. After that, I only encountered some minor issues, like

• the shadow of a textbox getting stuck on the screen and not disappearing even when starting a new run
• some glitches with the background music getting caught in a loop

Other than that, the game ran perfectly fine at 2560x1440@120Hz.
