Animation must have consistent motion, so in order to have a smooth animation (without interruptions or so called jank animation) you must achieve the special number, [**60 FPS**](https://www.algolia.com/developers-tech-blog/code-and-deep-dives/performant-web-animations/).

In order to play the game the player must only use the keyboard. The controls must be smooth, in other words you should not need to spam a key to take actions in the game.

We strongly advise you to use Developer Tools available in every browser (can be accessed using hot keys that depend on the browser or from the browser's Tools menu option).

In the developer tools you can also find a Paint Flashing option that will highlight every paint that happens in your page as actions are performed on it.
