How does you game fit the theme?
The game Zombie Apocalypse 3072 fits the theme your not alone because the aim of the game is to kill zombies and while your killing them there are random med-kits around the map assisting you and giving you an advantage

Did you write all the code and made all the assets from scratch?
I wrote all the code for the game and I used 2 assets one was for the map my friend got the asset which had the buildings almost premade he perfected them and put the map together, the other asset was movement audio. I wrote all the code myself from scratch
