This is a really cool idea! I like how distinctively different this feel from other sokoban style puzzles (I think that's what the box moving puzzlers are called, correct me if I'm wrong). Agree with audio being annoying, ripped off my headphones after fifteen seconds. I think the first two puzzles were really interesting, and 3 and 17 looked really cool too, but I couldn't manage to wrap my head around them and after a few minutes of poking around trying different things I called it quits. Difficulty curve was too steep for me, but really interesting mechanic!
