Nice little entry! Looks very good, and a shockingly function packedmenu! Good work. Regarding the gameplay: I think it's fun, and I think controlling the vehicle is fun, which is very important for a game like this, the game loop and the idea is good, however as others mentioned: at first is wasn't exactly clear what should I be doing, I almost gave up. I know game jams are so limited, and I also always struggle with adding a good tutorial, but here I think it would add a lot.
Nice work!
