Quite a nice little game. I liked the interplay with the mechanics, where you often needed to pick up the ducklings in a certain order for maximum points. It had a good risk/reward balance. The music speeding up was a great touch, it really added to the chaotic feeling of the game.
There are a couple of things you could do to help polish the game up if you wanted. I'd suggest adding some kind of counter at the bottom that tells you the number of ducklings in the level, and their types. It would help to plan the position of ducklings in the chains, and would give players an idea of how much time they had to work with. I'd also suggest increasing the cooldown on the ducks distraction. A couple of times I'd loose trails of ducklings around multiple distractions and it became near impossible to recover them, and with no restart button I was often left waiting the timer out before making a new attempt.
Overall this is a great entry, with some clever mechanics, and a really unique take on the theme. Well done!
