Please adjust lvl 7 so you don't have to do tight little circles near the center for so long. I had to adjust my cursor speed and was getting hand cramps.
I have just earned the second badge on the game, and I feel like it should have been a hard and not medium badge. About half my deaths were on that final level, and I died quite a few times. Then again, I'm crap at these bullet hell type games most of the time.
Thanks for reporting. Can you please retry, I fixed the problem.
