So far, so good. I think the difficulty is in a good place for Gold stars, and I've seen solutions posted for at least 12 or 13 Platinums so far! Great work everyone, truly impressive.
I just pushed an update, v1.1.2, that removes a loot bag from both Deadly Loot and Last Line of Defense. This probably breaks a couple of those Platinum solutions, but I think it needed to be done.
Deadly Loot - Somewhere along the line, I added an extra gold bag in there. Not sure when it happened, but I can't even solve it worse than Platinum right now. Consequently, I removed the bag. Platinums should be very difficult and hard to find, and this felt too easy.
Last Line of Defense - A couple people pointed out that it was inconsistent that Questy could score a Platinum on a level by saving a loot bag and not even leading him out of the room. I added a path that allows him to exit through the south exit without a loot bag, and removed a loot bag from the bags available. On the flip side, it's technically not possible to get Gold if you somehow figured out a way into the North exit, but I think this setup makes more sense than the way it was previous.
