I didn't see any points specifically intriguing in bullet patterns, but good job on making the stages. Hope you have the audio working for all stages and hope to see more creations in stage designs.
The audio is having some problems from Dropbox which is causing a delay so the audio doesn't sync with the game.
I am also going to add a Level creator in a future update.
Thanks for the comment and feedback.
