I'm always impressed when people manage to do good UI work in a jam! Congratulations on this aspect, menu, tutorial and everything.
The idea of the game is really cool, but I found it annoying that you launch a car into a horde and only kill one enemy.
Another detail is that normally attacks have to have a quick response, here, even for a heavy attack (launching a car), the response is very slow.
Some physics bugs also occur when loading objects.
The 3D models used are beautiful and match each other very well. The game has a very eye-catching look and has a lot of potential!
