The code is okay.

The main mode has all the features - timer, high score, ordered score board, different layouts.

The other modes are more in testing and need some additional features, but are functional.

No motion sensing. It's far too complicated for such a simple game and a full time student with a job. A solution would be to make it on a tablet and whenever a climber hits a "hold", the person using the tablet could hit it as well, essentially doing manual motion detection. Could also click on a computer.

I encourage pull requests.
