I really like this one!! The graphics are simple yet effective, the sound design is crisp, and the gameplay is very fun. My favourite aspect was the unique mouse controls, which made this feel different from other bullet hells of similar design.
I managed to beat your posted score with a score of 2900. Pretty proud of that, it gets pretty crazy near the end.
I wish there was a little more enemy variety, but the fact that they kept speeding up was fine as is.
