Dear dudeshreyu,
thanks for your merge request! Two questions:

1. The file seems to be incomplete. Was the merge request on purpose?
2. The files in this repo are html files with games that teach maths to children (like how to add two numbers). Intention is to use them in a maths class, or to lean/practice at home. I guess your snake game would fit that description? I haven't seen it finished, that's why I'm asking.

All the best, Jacob.
