Resolve conflict files

[AditiPrabhakar]

I've tried to resolve the conflict, but there are some bugs, there should be a closing button to both of the icons (gradient selector and instructions) as they overlap each other and don't close until the page is refreshed

and i don't know why game is not integrating properly after the changes, i tried to find that out to resolve it, can you please analyze the code for that
