Good news, folks!
I am about to get started on the actual game. After encountering some bugs with the command line and fixing them, the page works well. I have a story and stuff ready. Now I just need to code the game and gather resources (graphics, audio, etc) to make the game polished.
I'll keep you guys posted. As for now, here is a screenshot of a test I did a few hours ago. The starting scene is different now, though.
