Added NOR, XNOR and Left Shift. The last one, multiplication, beats me at this moment. Feel free to try, and if you complete it, make a PR.

Sorry for this noob question, but
How to run your program?
I try to download Eclipse php for it but with no success.

Don't worry, it's not a noob question at all. Eclipse PHP is just an code editor. You'll need a web server to run php on. When I made the code this repository contains I made it for myself, so using php was convenient for me, as that's the language I know best. It would probably be better built on javascript as everyone can run it in their web browser without any server.

Anyway, I'll add a "build" file and a guide in the read me to the repository so that you can just copy/paste it into the browser.

See build.txt for the content and README.md for how to add the solutions to your save game.

If you have more problems, hit back to me and I'll see what I can do. With that said, I really hope you tried the levels yourself as that is way more gratifying :)
