I agree with PikonParadox, main thing I noticed off the bat was bullets and no plane, which although is a good indicator seems unfair and not something skill can help you with. I would suggest maybe a flashing indicator instead and then have firing start when within range. I found I wanted to drive my tank but I understand this probably intended for your game.
The movement of the planes was challenging, but at the same time didn't feel so much like planes and more like helicopters (rotating around you).
Great start and fun jam submission.
