Just a normal archery game. It'd be a real travesty if it were anything else... Can you get an S rank on every level (~20 levels) (Yes it's possible, I did it).

Controls

WASD - Movement
Mouse - Aim
Left Mouse - Hold to draw bow, release to shoot
Escape - Pause Menu/Settings

Playtime: ~10 minutes if you're not going for high ranks.
Hints (Crosshair does not indicate exactly where the arrow will go, it's just to help align your shots)
