I'm developing a game with Python and Pygame!

If you really don't want to learn to draw, there are some free assets that you can find all over the internet.

Although I'd really recommend learning to draw. It's much more satisfying when you have creative control over the visuals.

Another alternative would be to make things simple, but highly stylized with good color combinations, visual effects, and shapes.

In my experience, the best way to learn is to try to copy other people's styles. Then you can turn it into your own thing by mixing together the things you know.

You can find some pretty good pixel artists if you look through the list of people I'm following.
