Really really love this! Very challenging and rewarding, love the choice of music as well as the fact that the level is synced to it. The graphics are simple but it works perfectly, makes the danmaku easy to read. I love the bullet patterns by the way! It's not just aimed, but you've actually got nice flower patterns and stuff. Very nice.
If I had to complain about something it'd just be the fact that you instantly die and start over at the beginning of the stage. This is not a game design problem actually, just a skill issue on my part. I'll for sure come back and try to beat this, as it stands right now I died to the big boss on March 30th.
