My first rating of the jam, here we go.
I like the use of the theme! Really clever way using attacks of others to your advantage. It seems like the music and art are completely your own? if so, kudos to you. It might be not the flashiest art but it has this lo-fi aesthetic, I really dig it.
btw, you already have a fullscreen button that's built in by unity. You can disable the itch full screen button that's on the game page - they just overlap and are confusing.
