I really enjoy the thought put in to the various controls, especially the parry. It took me a while to grasp the explosions, but I commend you on an in-game tutorial; it was helpful! Once I got the hang of it, I had a lot of fun blasting around the stages. I would have loved a music track throughout the piece. I had difficulty understanding the store screen, perhaps some sort of inventory could help keep track of what power up you have. Great work!
