Update game.js

[shpetimaliu]

In this version, I made some improvements to the clarity and readability of the code:

• I shortened the code by using template literals ($ {}) to inject the value of the level into the text of the h1 tag.
• I changed the random line to get a random index from the color array, instead of using a random number and then looking up the color in the array.
• I combined the keypress and click events into one on function to avoid duplicated code.
• I used the every method to check that the player's colors match those of the game in the checkanswer function.
• I modified the startover function to set check.
