Thanks for playing! Concerning the accuracy that was on purpose, more like flares or fireworks in design. It's a rigidbody so it's affected by gravity to give it a slightly curved path and I thought it was funny to use a central_impulse force to make it move because it made the rockets able to spiral out of control if it hits something. I was originally planning on having several varieties of rockets but I didn't have the time.

Visually, it's a cool effect. I'm sure it's good for something, but man it was frustrating to have that level of randomness with the aim. Having a few varieties of rockets would have been super cool, hopefully you can make use of that in a future jam. I'd even say that having enemies in a game fire rockets of this style might be great, as it would still be some threat to the player, but with a bit of randomness in their favor.
