I’ve been back to every level and done all the puzzles there, and now I have a million “object” shards. These are very simple, usually wordplay related, puzzles which can be completed anywhere. Like “Cat-Toast Paradox” where you have to create something that fits the two “rules” that cats always land on their feet, and toast always lands butter side down. Create a cat, combine it with some toast, and you get – obviously – a black hole.
I’ve about 200 of these left to get through!
