Congratulations on your first game jam!
It feels incredibly nice to play, so fluid. I really like that camera angle, though tilting the camera down slightly more might help to see the bullets and where they are targeted. The overload of visual effects is really nice and suit the theme really well. I'm not a fan of that font though.
My only other comment is that you shouldn't feel like you have to apologise for your game, it's great entry! Nevermind about the bugs, it's a jam game, we understand :)
