The sprite you used for the cover image of the game, the character with the cape, I was hoping to see that in the game! Too bad! Couldn't figure out how the "loop" theme was worked into the game, but maybe I didn't progress far enough. I think the difficulty starts out quite high - I wasn't really given much opportunity to learn the bullet patterns or how it feels to move around and use the cards. If you reduce the frequency that the bullets are coming out for an initial stage or two, then speed it up to make it more challenging, I think I could have gotten better and played longer. Still, it's an original combination of mechanics to me, and it has potential to be a great game!
