didn't fully finish because I was too bad, but had fun trying it out anyway. Though I agree with the challenge part, making it a bit easier to aim diagonally (because that already works) would be nice, it's really hard right now.
It does add to the challenge. Visually, you could justify the decision by drawing the weapon as part of the character's chest, or putting them on a bike that the gun is mounted on. But only if you want to develop it more past the jam version.
