Epilepsy Warning Menus are opened and closed in rapid succession at multiple sections throughout the run.

The glitch performed requires the use of a controller. Specifically the small button opposite the pause button, which can open the restart menu even while a level is ending. It works really well on level 1 the furthest I got was level 12. On any other level you can only skip ahead one level further.

To my knowledge this isn't possible on keyboard as the menu in the top right disappears.
