Firstly, thank you for the answer.
Secondly, a web version isn't necessary to try it out, as a windows build would be sufficient, but I understand so ok.
Thirdly, what do you mean run it natively, what will it need to run on? A Linux? Windows? Web? Something else? If so, are you 100% certain that Godot can in fact compile it into a correct format?

Also about the 12 keys, what those?
Arrows and AB twice?

For the controls, we do not need to use all of them, right?
Thanks!
