Its a start for you. If you want to make some really cool game Pick a 2d game engine and Learn everything. Also even if you are not an artist simple block will work. Not everything has to be well detailed.
I suggest take a look at construct 2 or what is it now construct 3. Its a fairly easy game engine and it has alot of bell to help beginner out.
In a 2d game, Its very important to blend artwork that match up with control. Im sure you played some games. They are usually made by a group of friends or coworker. In a sense. pic a direction to go and practice and learn. If you just want to be a dev then learn to code. if you want to be an game designer. Learn to draw and learn the various program to make art. If you want to be a game music composer then go with it.
You cannot be all three at once. Master one at a time.
Also you might want to follow this practice before you make your next new game, and that is to Learn to credit who made the artwork. Or ask the creator about the artwork, I got flamed for it in the past and now i dont do any coding work for any game unless if i get proper credit and permission from artist.
