Adapting a Game for Mys?

[squiggler]

Hey. I found an open-source game called 2048. It's under the MIT license. (I'm pretty sure this means that any mods we make will be open source as well.)

I want to adapt the code to make it look like this game- with the pictures instead of numbers. (I can't use that site to make it because of their TOS.)
I've figured out that it probably would be edited in the style folder, but can anyone help me decode it?

Also, I would like to do one of two things: send score to get promocode to get money, or have you automatically earn funds as you're playing. There would need to be a cap on this, obviously.

Thank you in advance for any help you can provide!
