Music & sound are good,
graphics are nice.
The gameplay could use some work.
I wouldn't recommend mouse controls for a Shoot-Em-up, or a Bullet hell,
it makes the game feel a bit clunky. It could be alright if the ship wasn't really slow and highly responsive to the mouses precise inputs/movement.
I assume the upgrades make it faster eventually, but still; to start of with, it's really slow.
The parry mechanic is great, but I feel like the amount of time it sits on screen could be slightly longer.
Slick work!
