I just found TIC-80 recently and have been coding a turn-based strategy game. I use TypeScript which I then compile into Javascript and paste it into TIC-80. So far, the coding limit hasn't been a problem, but if it becomes one, I can optimize the generated code for size, and minify the JS which will, typically, drastically reduce the size of the code. I don't know if other languages have minifiers, but I suspect they do not because the impetus for developing minifiers for JS does not exist in most other languages, that I am aware of.
