It's really weird we are exploring the same genre.
Yeah seriously. I was inspired by a different disk-flicking game I made last year (http://noisyowl.com/disks/), which in turn was inspired by the board game Catacombs and the shape of the board in Hearthstone (it's an interesting shape; bouncing things off it is more interesting than waiting for your opponent).
You said yours was inspired by Into The Breach... how'd you get there from that? Is your plan to continue doing something like a tactics game, but with bouncy disks?
