“How can I get better at making games”, you’re asking? Well, at least part of it is easy: Play the games other people make.
But don’t just play them, pay attention to what you like or dislike about them and why. If you attentively play enough games, this can give you a good overview of what works well and what doesn’t. Find out what makes a game fun or enjoyable to play for you personally. There’s a good chance that (at least some) other people will agree.
If you don’t know where to start, you can (warning, self-promotion!) check out my latest games here and here.
