68.4 seconds but I finally caught that sucker!
First up, I really thought it was clever that you built upon last year's Jam game. In all the jams I've done, I'm not sure I've ever seen anyone do that... I certainly haven't though of it but I think it's a great idea to revisit your old code! Second, I liked the tank controls. Driving felt nice and responsive which made me think I had a good chance of catching that missile, even if it took me forever to do so.
I suppose if I have a criticism it's that I feel a bit cheated when I'm chasing the missile, it hits a border wall and then respawns super-far away from me. It kind of feels unfair, though I'm not quite sure how to refine it without making the game too easy.
Overall, great job. I enjoyed my time playing it.
