this game got its own (sub)domain!
Despite promises in previous note, I still moved on and added "easy" and "real" modes. Why? Because I realised that choosing next step over and over again gets tiresome soon, and artificially limiting game time makes the game more... interesting . How is it working? Well, I've been playing it for one week so far, without missing any time slots (with 10 hour "travel time" between stars I'm effectively limited to playing it twice a day: in the morning and in the evening, ±2 hours from usual time).
Also, regarding animations: I've added some of them, but not sure if I like them or will change them. We'll see!

Note that if you previously played this game on this website (in iframe or on an individual page), then your progress (for "hard" mode, since it was the only game mode before) will not be transferred to the new site. That's the drawback of storing data locally in the browser. If you need it - please ask me - I'll send you instructions on how to fetch your progress saved for one site and inject it into another.
