First of all, a huge congratulations to you for your first ever game jam project. I loved the combo of witchiness and girly flair in the character, not to leave out your wonderful graphic designing skills. The scene was soothingly colorful. The characters were well-animated. The only thing that bothered was the jumping and shooting. But well, it's your first jam & considering the amount of time you've put in graphics, I'll give you a pass on the mechanics.
All in all, really well-done. Keep it up. You're gonna do awesome in your next jam!
