Got confused at first, but once I got the hang of it, I loved the puzzle element of it. My confusion came from the fact that I got the first shot right by accident and did not know I had to climb the ladder.
Great feedback! We're working right now on fixing those issues. We definitely want levels that intuitively teach the player the core mechanics, rather than coming across as mere accidents.
