OneShot allows you to practice and increase your shooting skills over 50 levels in fps mode. But be carefull, you have just 1 bullet for each level. If you miss the target, you have to restart from the beginning.
But control is annoying. Instead of doing delta for movement, you should be able to select specific, so you can drag and scroll.
