Difficult but fun game!
I liked the laid-back music and the cute little sound effects.
Also, the snarky comments when you lose was a nice touch! Made me chuckle.
The graphics were cute and the particle + enemy effects look great!
One thing I was having trouble with is the bullet colors. Sometimes I would confuse my bullet with the enemy bullets, especially as the game gets more hectic + difficult.
Also, just a personal feature I would like to see, would be a boss health bar, but it is not needed.
But everything else was great!
Good job on this! :D
