This was a really interesting game. I loved the art style! The gameplay reminded me of a 2D CoD Zombies, I had a load of fun playing it! The only issue I had was that I couldn't figure out how to activate fullscreen until I read another comment on here, I didn't see the box for it either. However, the game ran perfectly without being in fullscreen so it didn't impact the gameplay.
I definitely see myself coming back to this game when I have some time to pass between tasks. Great work!
