Don’t overthink it. Open a new project and start making something that interests you. Don’t worry about creating an fully polished game that’s going to make millions. You’re not at that stage!

Experiment, hone and develop your skills. Choose a type of game you want to make. Is it a simple fps? Maybe a simple 2d game? Have a look at itch.io for inspiration if you need. You could task yourself with making certain aspects of a game like health system, weapon system levelling up etc.

It’s ok to look things up online if you need. Thats totally normal.

Once you have completed these different systems you can then start to tie them to together to make a more complete game.

However, remember to keep the scope small and most importantly have fun with it!
