The ability to get a high score in rhis game is completely dependent on RNG. Any actual skill is useless since half the ghosts you encounter are practically death sentences as soon as you see them anyways; particularly the pink ghost when it is off screen. And good luck trying to chain 256 with so many gaps between the dots. You can also pay in-game currency to continue after you die, but the issue is, the amount you pay increases each time you use it, and it does NOT reset after a game over.
