Really enjoyed this. Thanks for creating it.

#7 is my personal enemy. Maybe it's just me but it was hard to pin point the exact number on a smaller screen.

Maybe increasing the the font size of the numbers or increasing the duration between each movement might help.

Sorry about that! Based on other feedback too, I was thinking of maybe reducing the digit count from 6 to 4. It should be enough to prove you're able to solve the puzzle, but less frustrating.
