Good job with the zombie smashing mechanic; really needs some sound effects though, and maybe some zombie body parts being catapulted up to the player camera. Unfortunately I didn't really get far, I was approached by plenty of zombies right away and had to smash the mouse really hard to survive for a bit. That's a pity, because I wanted to explore the map further and see if there was anything else I might have missed. Some progression would be helpful if you plan to continue working on this.
