I find it hard even though I am somewhat used to them since my first language is Korean. Hardest part for me is remembering the character shape and their associated sound. The general concept (kunyomi and onyomi, how they form words) makes sense though.
If you haven’t used Sunshine to play games yet, I would first try it out with whatever equipments you have before going all-in. It sounds fucking cool on paper, but the whole experience wasn’t all that great for me. Not the Sunshine’s fault, but the games I play are very latency sensitive that it was barely playable.
Personally, if the games play well, I would just go for it.
You should check out .gitignore templates and .gitignore file in other open source Android apps to see what needs to be published, what doesn’t need to be published, and most importantly what you should not publish. You should get a couple of results when you search “gitignore android studio”.
