Ooh that's a cool idea, that could make a very interesting game. The current thing I'm working on has to do with movement mastery, as a hint
If you're talking about what the goal of the game will be after the next stuff is added, I'm not too sure since we're still testing things. The elevator pitch of the game though is 'a peaceful and exploratory game' so it might have something to do with reconstructing gems, exploring and experiencing beauty, etc
It's not a super 'gamey' game with goals based around linear progression, points, etc but I might add some fun systems, we'll see where it goes
