Great artwork. And I really liked the mechanics. I thought the Sheild, Dash, and Shoot were a good scope for a game jam. And it was fun just to jump right into a boss fight. I'd love to see what a full game would be.
My only real feedback was that I wish the buttons were switched. Spacebar for Dash and Shift for Sheild. I was dashing so much more often than shielding, and my thumb is much better equipped for that.
Cheers. Nice game.
