Thanks!
Currently I'm not planning to make this open-source. Mainly, because I was too lazy to keep it up-to-date with recent changes to the engine, so right now it wouldn't even build.
Also, this game mainly targets javascript and is therefore completely single-threaded, so not much to learn there. I believe the engine examples on github are actually a better starting point than this game here.
Hmm maybe some settings got messed up. You can try to clear your browser's localStorage like, for example, described here:

if the F12 key does not work you can also open the console via the menu button (the one with the three dots) in the upper right corner and then going to "more tools" -> "developer tools".
This will probably also delete your save games though.
