Light runnerrrrrrrrrrrrrrrr

So ive been making an obby runner game, idk what to add do it so can someone tell me

The game is very buggy on mobile: the right and left buttons are switched, once you die in the void, the button which would guide you into that direction seems to be stuck, meaning that you die everytime unless you press the button to go into the opposite direction (again, if you let go of this, you’re gonna die)
