Nice clean idea, curling rules turned into a sliding block puzzle works really well, and the "Takeout!" confetti is a cheerful touch. One thing I hit on level 2: I pressed Up then Left quite quickly, and the second press seemed to land while the blue stone was still being knocked off, which gave me a Try Again. Doing it slowly worked fine. Buffering the next input until the slide finishes would make keyboard play feel a lot smoother. Looking forward to seeing how the later levels build up.
