Very similar to this one. Which is a good thing, as I really like the idea. :) Love the variety of faces, like the highscore mechanic that rewards you for being quick and found it especially clever, that you can also miss the target, if you're not aiming carefully. Fits the theme ("only one shot") and prevents you from only focusing on the features displayed in the sidebar and aiming with peripheral vision only.
