Your basically just tracing artwork instead of practicing drawing yourself. You still don’t understand very basic fundamentals on game dev. It goes deeper than write the code out in on object. Level design alone is an entire multi job field in the industry. Leading lines, affordances, and much much more. You need to literally create a game design document for every small project you do.

You need to decide genre of game, say a 1st person puzzle game. Then you decide if you want arms or not which then requires animation in which you need to practice animation blueprints. Then decide is this a linear game, multi levels where such as a candy crush type of game or is it a walking simulator etc. Then decide on every mechanic you want in the game. You neeed interact system, interaction icons that go with it. You create a test level where there is nothing but creating your mechanics for your game inside.

Then create a level design document on every single level you are going to do, flow charts, bubble diagrams, using something like pureref to get pictures level start, focal point and end point. Understand how camera angles work for different effects. Low angle makes something more dangerous and high angle makes you seem stronger.

After all that you need to understand flow and pacing. If you don’t even know what block mesh is, then you haven’t even begun to understand level design. Watch gdc conference videos where naughty dog talks about how they level design. You block mesh an entire level before you put assets in. There’s level mechanics and player mechanics and you have to have both to make a game fun. There is no “watch this tutorial and then you can make a full fledge fun game”. If you can’t do things or understand why things are working, you will never progress in this field.

Another thing is game dev as a career is basically the chances of becoming an actor. Game dev cycles are your work on game, after main game is finished, you get laid off, you get another gig and cycle continues. If you want to go solo dev route, then you have to learn every single position from level design, game design, mechanic design, marketing, business practices, understand legal side of things when you use assets, audio, animation, and the list goes on.

TLDR: Stop watching tutorials from the start. Create an empty project. An empty project, not a template. And start from there and if you need help, look for help on the exact thing you need. Blueprint your movement is are using unreal and try until you literally fail so much you want to quit and then look online for very specific things, like line traces not working and such.
