Neat! There was actually some skill involved with trying to pierce my shots through multiple numbers, though it did feel also a little bit as though I needed to get an amount lucky with the angles of the 'boss' spawns. I wasn't able to find any major bugs in my hunting, but when I lost while holding down the mouse button the bar continued to charge up for several seconds before I was booted back to the main menu which was at least a little bit funny. Great work.
