Score is now implemented -enjoy!

thanks!

edit: you broke it :(

Fixed! The score is now calculated as the sum of all merge results (like the original game), instead of the sum of all cells (like I was doing).

As a bonus, the score calculation is now done in pure sed.

If you notice any other issues, please let me know!

thanks

One final gameplay tweak: there's now a 90% chance that a newly-spawned tile will be a "2" and a 10% chance that it will be a "4".

The gameplay should now be identical to the original 2048.
