Trapped in a cave. Laser things shooting at you. Buttons everywhere. Spikes even more everywhere. It's a normal day for our featureless friend in Focus, a puzzle platform game originally by Karoshi author Jesse Venbrux. Ported to the browser world by Joseph Ivie, Focus features over 50 levels of extra difficult action, sticking you in enclosed rooms with all manner of dangers and challenging you to use your platforming skills to make it out alive.
