This is an amazing game considering the time limit. It is already engaging from the start and the detailed tutorial. Each level made me pause and think, but really fun to play. I love playing puzzle games. I always wanted to create one, but it was very challenging for me to come up with difficult and also reasonable puzzles. That's why I think this game did a very great job on level design and shaping simple mechanics to complicated puzzles.
The scene transition is actually interesting and creative. But I personally think the blocks fall a bit too fast, which makes the transition too dazzling to watch on screen.
