The text is almost exactly the same (minor changes to instructions, about pressing the buttons instead of using keyboard keys, and target moving left-right instead of up-down). And I hope the programs work exactly the same as well. Let me know if you see any errors, differences from the old versions, or experience some bugs.
I’ve left the ‘under construction’ note because there might still be some changes to the code. It is open-source (MIT) licence, feel free to modify, change and tinker with the code, or use it in your own projects.

I’ll probably upload these to github eventually. If some of you are js programmers, let me know if there are ways of improving the code.
