Apparently I need a tutorial lol, the dice button in the top middle of the screen roll's through all the dice faces and puts you on a random one. I'm working on making resources have more used than just upgrading a single planet rn.
I found it pretty clear, but that could also be because I missed some things, I only used the upgrade like right bottom, and the roll in the top middle. But I would suggest looking into your randomness, as I got every single cube type in order (like on the left side, that exact order). It could be a stroke of luck, but I'm not sure about it. (even on the updated one, I got the magma then fish so like its ordered).
I would think a tutorial should be added pretty late in the game, so you know what direction your going in, as if you add some features that replace old ones, then your tutorial might be outdated, and you need to update it again.
Good luck on making them useful for multiple planets, I wish you luck with both creativity and the building of the game.
