There have been a lot of comments with the request of offline progress. But I don't think that fit with this game - I love to play it when I want to, not when I have to.
Energy system is not that bad, guys. It gives a chance for everyone to progress based on your activity, not the amount of time you can spend at one session. Best energy-based game I've played so far, to be honest.
Wow, I don't really have any words for this game. It's a gem amongst all gems, almost made me cry at the end. Love the concept of having a unique meaning to the game, and teaching us a bit as well - like the old games did :)
wait xD this is game breaking bug! EDIT:fixed!
