HTML works, you just need to go in the file and click on "project". And I haven't got Linux, so I can't fix it right now... And you can't click with mouse. You need to click with the player with space. Then you can start the game.

Edit: I updated the game page, now everyone can see how to launch the game and how the controls work (:

Yes it is. I just converted to .exe, like this: sb3 -> Html -> .exe

You can do that, too: https://nwjs.io/downloads/
