Thank you very much for your feedback !
Firstly, I don't really think I will expand it to mobile, even if it works, but maybe one day...
And also I know there is not so much content right now, mainly because it was my first game in Godot, so I made this to learn about it and I actually leart. I don't know if there will be updates, because I would prefer to work on other games if I get some ideas, but if I have some time why not ?
