Interesting game!
It is a bit tricky to play and also a bit too hard for me.
Managing both shields is very very hard, its like drawing 2 different drawings with both hands.
Music and sounds are good, they fit the theme.
Would have loved a scaling in difficulty, as right now it feels random how fast some projectiles are. So in turn the difficulty becomes very all over other the place.
Nevertheless, great job! Please do keep making games!
