Thanks for the suggestion, but I really, really dislike voice to text input.

I use Microsoft SwiftKey for the same reasons, find it hard to switch or get used to anything else.

Having used SwiftKey since before Microsoft acquired them, I’m a little annoyed at all the shit they’ve tacked onto the keyboard (like no, I don’t need Bing and ChatGPT in my keyboard, thank you very much). But nothing else let’s me mix languages in the same way as SwiftKey.

I never did Rails but I used Ruby for many personal projects in the 2000s.

When showing stuff to my coworkers or friends, I often joked how I tried to make my code look like it was already gzipped.

That is oddly specific put pretty accurate

It’s by no means perfect, but Lua with LÖVE is pretty straightforward for 2D games, and gives you a Real™️ programming language as well.

Alternatively, Godot is a modern open source game engine and framework, and if you stick to 2D and the built-in GDScript, it comes with a lot of nice things for creating levels, maps, animations etc. However, perhaps for a 10yo the barrier to entry might be a bit high.
