You need to allow Scratch to use your camera to play this game. See below for more information about the Video Sensing extension. Point the hose at the fires to put them out. Wave your arms at the camera to clear away the smoke. Once all three windows on a floor are on fire, they can't be put out. The game is over when all windows are on fire. The camera is always on, but you can click the camera icon to toggle video visibility. The objective is to last as long as possible. There is no cloud highscore or leaderboard. Unfortunately, even if cloud variables were working at the moment, projects that use the Video Sensing extension, can't use cloud variables. All code by me (@kriblo). ===REGARDING_VIDEO_SENSING=== You need a computer, tablet or phone with built in camera, and you need to click "yes" when asked if Scratch is allowed to use your camera. If you don't get this question, it's likely you've been asked before on the same computer. If you have answered this question "no" in the past, this can be cleared in your browsers settings.
