I liked the sound effects, they add a lot of charm. The music was a bit too loud for me, though, so I ended up muting it.
The gameplay has some fun intensity, but it felt overwhelming at times. The projectiles are really fast, making dodging tough. Slowing them down a bit might make the challenge feel more fair. (although looking at Brainoid's score it looks like I'm just bad) Also, the amount of projectiles I could shoot was kind of wild.
Overall, it was a bit chaotic but fun. Great job for a jam entry!
