Looks like we both made a tank game for this jam.
In some ways I kind of feel as if this is the opposite take of my game. In your game the movement is controllable but the recoil is not. In my game the engine moves erratically but you need to use your cannon's recoil to somewhat direct the tank.
In both cases though... it seems both of our games are... "shoot to move"
(Took a few tries but I finally beat the final stage)
