First off, 10/10 voice work. Sold me on the tone of this game - a wacky shooter with car steering mechanics. The aesthetics of the game felt pretty Mad Max-like, especially with all the bullets.
The choice to make the main character a half-wizard, half-car is a bold and creative one, and I applaud you for that!
I appreciated you using the car steering controls to better reflect the car-half; however, I did find it a little unwieldy when playing the game from a bottom down view. The turns are all relative to the position the cartaur is facing at any moment, so it took me a while to get used to.
I liked having the choice between the two wizard abilities (attack and block/grab). If you plan to expand upon this, I think it would be cool to have the ability to charge attacks and/or run over enemies. And since the character is half-wizard, there's a lot of potential to expand the cartaur's magical abilities. Overall nice job with this unique spin on the theme!
