This was pretty impressive for your first Jam game, it felt challenging (especially if you wanted to get a high score) while still being fair! Presentation took a bit of a hit because of the music and saturation, and I wish it had been a bit clearer how many times you could freeze your line (I only noticed the counter for it on the actual last level...), but this was one of the most fun ones I've played so far and used the theme in a creative way.
