Hey Sokky! Fellow visual artist here.
I strongly suggest picking up Construct 2 or Twine and signing up for a bunch of game jams. Forcing yourself to make a lot of tiny games is the best way to grow as a dev. (Remember the old adage: "Your first ten games will suck, get them over with")
If you ever need any help, hit me up. I'm pretty busy as a rule, but I'm happy to answer questions.
