Very well polished experience. The game is a bit boring on the easiest difficulties and I ended up giving up halfway in the Casual mode after ~15 rounds as while having only fruits&ducks makes it easy to build patterns and the slow expansion of the countdown gives you more than enough time to memorize them. However on the hardest difficulties, it works pretty well and proves to be quite an addictive challenge (even if the run I did still ended up taking quite a fair bit of time).
