This one had some fun puzzle/level design. I liked having to defend myself from the rockets as I explored solving the puzzles. It added some pressure that games like this don't usually have. The grab and drop mechanism could use a little polish still -- in particular for me, I would have liked to grab them from slightly further away so that I could build bridges a little faster once I realized what I had to do. The rewind gun was a cool idea, too, but its uses were rare and a little unintuitive. Nice work, overall!
