Quantum Conundrum released today, and I'm thoroughly enjoying my time solving these puzzles, and hunting for collectibles.
Being a completionist, I hate the idea of missing a collectible (especially if there is an achievement involved).
Just how many are there? If possible, where can I find them?
Note: I am not asking for detailed information on each collectible. A simple "This chapter has this many" or something of that sort will suffice. In the event the total number of collectibles is too high, I will be removing that part from the question.
