You did not follow the theme of the jam. The graphics are pretty good and the sound and music is the best part. The gameplay however was frustrating I'm really not sure how you were supposed to avoid the enemy's that shoot back.
yes, I really didn't follow the theme, I was going to add another element that did, but ran out of time. And also, to avoid the shootie enemies you spam back, (because then your bullets will collide with their bullets) or jump over their bullets.
