Thanks for the reply!
Just a small tip: itch.io actually has its own fullscreen button if you enable it in the game page settings. That way players don't have to open the in-game settings first (or zoom in because the game starts out pretty small).
Also, since you're already supporting two languages, I'd recommend making English the default language. It will probably be more accessible for most players on itch.io.
Other than that, I really like the idea! The 10 levels with 10 different tactics is a cool concept. The only thing I'd say is that it can feel a bit hard or demotivating if you have to start from level 0 every time. Maybe some kind of level select or checkpoint system could help in the future.
Overall, though, it's a cool game. Keep it up!
