Thanks so much for taking the time to check out our game. Great feedback. We did indicate that "R" will restart the game, however, we've been thinking it might have been nice (if we'd had the time) to have added button or mouse click to cancel an unwanted shot that was lined up. We made some changes late in development that seemingly and accidentally made the game a little more challenging than we had hoped but hopefully it's still a good time. :)
Thanks again for playing. :)
