About Physics Knife
Take knife like a real thing and interact with it. Throw, rotate your weapon and etc.
How to play Physics Knife
The opening minute doubles as the tutorial. You will want a keyboard for this one — the arrow keys / WASD carry most of it, and the table below has the rest. The game is wide rather than tall — fullscreen is worth it on a monitor, and on a phone the picture is much better sideways. Expect the first attempt to be a write-off; that is normal here.

|---|---|
| Mouse | Navigate menus and interact |

On mobile: Tap and swipe on screen. Turn your phone sideways — this game is designed for landscape and fills a horizontal screen.
Why it is worth playing
Difficulty in Physics Knife comes from the game itself rather than from waiting, unlocking or paying, which is rarer than it should be. That is the whole pitch, and it is enough.
