I agree with you about the tradeoffs that C# and Java make to gain ease of use at the cost of memory use. In a lot of cases that's a fine tradeoff. It doesn't matter much too me whether an indy game needs a little more memory. I'll also agree that C is going to be less safe than Rust (and Java, C#). But I still think it's an easy language to iterate in. It's a very simple language.
