Reminds me of Hotline Miami, definitely a cool concept. Had a good time playing handgun catch with the zombies. BTW, itch provides an option for adding a full screen button in the game settings.
Thanks for playing :) yeah hotline miami was the main inspiration here, i didn’t really have as much time as i wanted for it though :( For me when i open the game there already is a full screen button at the bottom right, not sure what that issue is!
