Clone of the game "Tanks"

Question

JavaScript

Hello everyone, I'm writing in haste.
I recently decided to practice a bit in prototyping and write a small toy (Tanks) in pure JavaScript (none of the plugins are connected).
As a result, everything expanded to somewhere up to 1,500 lines of code.
Now the map editor with saving to localStorage and the game itself have already been implemented. The game implements checks for collisions with blocks, map edges, to put it simply, the tank already travels only where it is allowed.
I wanted to ask you one thing, can anyone want to connect to its development? I understand that picking someone else's code is a dirty business, but I commented everything, it will be easier.
PS I'm a student myself, I work, so I can't spend a lot of time on it.
