Short and silly! The way the coffee cup gets upgraded to look like more of a badass is quite fun. I would recommend balancing the zombie movement a little better, there quick speed and pathing straight for the player meant it took me 4 or 5 instant deaths before I could figure out what to do. And maybe you can add some stronger enemy types as the game goes on? Like a slower, more tanky zombie? But this is a great start, nice work!
