Thank you! Yeah, by default the game assumes a QWERTY keyboard or a controller.
We’re aware of the strange behavior where full screen makes the game center in a strange way. I’m looking into what I can do to change it.
The ‘Chain Reaction’ theme was meant to be encapsulated in the story (server maintenance -> D.A.D. walk -> cowboy shootout) as well as the ricochet mechanic, though only the starting revolver has ricocheting bullets.
I’m glad you enjoyed the art–our artist worked hard on it. Thanks for playing!
