It's really beautiful, and the audio design is very well done. But I found the first stage really hard to figure out, I couldn't understand the rule that makes the bomb blow up the box; just when I thought I had it figured out, the box wouldn't explode. But the bullet hell part was really well done and a lot of fun. Too bad that since I didn't do well on the first fase, the second one is way too hard for me, lol.
