Thank u for your time!
I use JQuery to make it easier for me to select and perform multiple actions (chain) on some of the game's elements. However, I have learned with time that it wasn't too hard to do the same things with pure JS, therefore, I'm thinking of removing JQuery.
Well, I do use use SetTimeout() on many parts in this prototype.
I do use that hiding technique by setting the display="none" as well. As for remove, I use it on elements I don't have need for.
