There are also a couple of reasons why someone might want to use a substitute for rice.

Growing rice is very water intensive. Rice contains traces of arsenic. And of course it's full of carbohydrates.

The packaging is marketing and uses the same plant-based stick that is conflated with healthy food.

I would suggest that you try something different. Do a little tutorial game in the Godot engine and learn all the things that you would need to implement yourself if you wouldn't have the Godot engine doing the heavy lifting for you. This might help you to get a feeling for the scope of your endeavor. I think it's hard enough to build a game where you don't have to implement sprite movement, update ticks, physics, collision detection, etc yourself.

If you want to do it anyway because it's awesome, there's a running joke that there are like 50 game engines currently being developed in Rust. Go all in!

The thing is, I also want to query all possible colors. And that would then be in a different function so I'd have to change two functions whenever I add a new color and I don't like that.

I heard about this, but I wasn't sure it was the right way. Or if Rust developers just straight up avoid situations like this.

If you go down the Java route you will probably end up working with enterprise/legacy software. If you are fine with that, do it. But what's wrong with focussing on JavaScript as your main language?

The YouTube algorithm is sometimes surprisingly good. Like "Listen to this band with 47 plays!" and then it's a banger.
