Have I mentioned that Steven Universe: Attack the Light is a great game? Because it is.

I went back to it to try shooting for 100% completion, and I'm very nearly there. The Gems' levels are all maxed (though I didn't maximize all their abilities, turns out those upgrades are missable and that's a bit of a flaw), Steven's level is almost there (I think he just needs two more levels, but he levels really slowly and I think his only remaining bonuses are upgrades to Escape, which I don't use or need at this point). I also found all the badges! I have 100% on four of the five worlds, but I've encountered a problem with World 3.

See, each World has two secret levels that you access by using rare Gemstones to unlock doors in the normal levels, and to unlock the last secret level in World 3, I need a Red Gemstone. Unfortunately, I can't seem to find any more Red Gemstones. I haven't been able to find a good online resource for this game so I've been going back through the levels and checking the shops scattered around, but unless I missed a shop (I don't think the secret levels have shops so I didn't check), Worlds 3, 4, and 5 are fresh out of Red Gemstones, and I remember a character very clearly saying we won't find them in World 1.

I'll have to investigate World 2 next, and then maybe double check World 1 and the secret levels, but I'm starting to worry this level might be missable. I don't suppose anyone plays the game and has any idea where I could find the Gemstone I need?

Also since I haven't been able to say this anywhere else, I love the final boss of this game so much, I think it might honestly be my favorite final boss of any game I've played and I really hope it somehow turns up in the show (though it probably won't).

EDIT: Okay I found it, there's a shop in a secret room in World 2 that had that last Red Gemstone, bought it and cleaned out the last zone. 100% completion ranking on all 5 Worlds!
